A port is a maritime commercial facility which may comprise one or more wharves where ships may dock to load and discharge passengers and cargo. Although situated on a sea coast or estuary, some ports, such as Hamburg and Duluth, are many miles inland, with access from the sea via river or canal. Today, by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhoushan. Whenever ancient civilisations engaged in maritime trade, they tended to develop sea ports. One of the world's oldest known artificial harbors is at Wadi al-Jarf on the Red Sea. Along with the finding of harbor structures, ancient anchors have been found. Other ancient ports include Guangzhou during Qin Dynasty China and Canopus, the principal Egyptian port for Greek trade before the foundation of Alexandria. In ancient Greece, Athens' port of Piraeus was the base for the Athenian fleet which played a crucial role in the Battle of Salamis against the Persians in 480 BCE.
In ancient India from 3700 BCE, Lothal was a prominent city of the Indus valley civilisation, located in the Bhāl region of the modern state of Gujarāt. Ostia Antica was the port of ancient Rome with Portus established by Claudius and enlarged by Trajan to supplement the nearby port of Ostia. In Japan, during the Edo period, the island of Dejima was the only port open for trade with Europe and received only a single Dutch ship per year, whereas Osaka was the largest domestic port and the main trade hub for rice. Nowadays, many of these ancient sites no longer function as modern ports. In more recent times, ports sometimes fall out of use. Rye, East Sussex, was an important English port in the Middle Ages, but the coastline changed and it is now 2 miles from the sea, while the ports of Ravenspurn and Dunwich have been lost to coastal erosion. Whereas early ports tended to be just simple harbours, modern ports tend to be multimodal distribution hubs, with transport links using sea, canal, road and air routes.
Successful ports are located to optimize access to an active hinterland, such as the London Gateway. Ideally, a port will grant easy navigation to ships, will give shelter from wind and waves. Ports are on estuaries, where the water may be shallow and may need regular dredging. Deep water ports such as Milford Haven are less common, but can handle larger ships with a greater draft, such as super tankers, Post-Panamax vessels and large container ships. Other businesses such as regional distribution centres and freight-forwarders and other processing facilities find it advantageous to be located within a port or nearby. Modern ports will have specialised cargo-handling equipment, such as gantry cranes, reach stackers and forklift trucks. Ports have specialised functions: some tend to cater for passenger ferries and cruise ships; some third world countries and small islands such as Ascension and St Helena still have limited port facilities, so that ships must anchor off while their cargo and passengers are taken ashore by barge or launch.
In modern times, ports decline, depending on current economic trends. In the UK, both the ports of Liverpool and Southampton were once significant in the transatlantic passenger liner business. Once airliner traffic decimated that trade, both ports diversified to container cargo and cruise ships. Up until the 1950s the Port of London was a major international port on the River Thames, but changes in shipping and the use of containers and larger ships, have led to its decline. Thamesport, a small semi-automated container port thrived for some years, but has been hit hard by competition from the emergent London Gateway port and logistics hub. In mainland Europe, it is normal for ports to be publicly owned, so that, for instance, the ports of Rotterdam and Amsterdam are owned by the state and by the cities themselves. By contrast, in the UK all ports are in private hands, such as Peel Ports who own the Port of Liverpool, John Lennon Airport and the Manchester Ship Canal. Though modern ships tend to have bow-thrusters and stern-thrusters, many port authorities still require vessels to use pilots and tugboats for manoeuvering large ships in tight quarters.
For instance, ships approaching the Belgian port of Antwerp, an inland port on the River Scheldt, are obliged to use Dutch pilots when navigating on that part of the estuary that belongs to the Netherlands. Ports with international traffic have customs facilities; the terms "port" and "seaport" are used for different types of port facilities that handle ocean-going vessels, river port is used for river traffic, such as barges and other shallow-draft vessels. A dry port is an inland intermodal terminal directly connected by road or rail to a seaport and operating as a centre for the transshipment of sea cargo to inland destinations. A fishing port is a harbor for landing and distributing fish, it may be a recreational facility, but it is commercial. A fishing port is the only port that depends on an ocean product, depletion of fish may cause a fishing port to be uneconomical. An inland port is a port on a navigable lake, river, or canal with access to a sea or ocean, which therefore allows a ship to sail from the ocean inland to the port to load or unload its cargo.
An example of this is the St. Lawrence Seaway which allows ships to travel from the Atlantic Ocean several thousand kilometers inland to Great Lakes ports like Toronto, Duluth-Superior, C
The Rhineland is the name used for a loosely defined area of Western Germany along the Rhine, chiefly its middle section. The Rhinelands refers to a loosely defined region embracing the land on the banks of the Rhine in Central Europe, which were settled by Ripuarian and Salian Franks and became part of Frankish Austrasia. In the High Middle Ages, numerous Imperial States along the river emerged from the former stem duchy of Lotharingia, without developing any common political or cultural identity. A "Rhineland" conceptualization did not evolve until the 19th century after the War of the First Coalition, when a short-lived Cisrhenian Republic was established on territory conquered by French troops; the term covered the whole occupied zone west of the Rhine including the bridgeheads on the eastern banks. After the collapse of the French dominated West Bank in the early 19th century, the regions of Lower Rhine and Jülich-Cleves-Berg were annexed to the Kingdom of Prussia. In 1822 the Prussian administration reorganized the territory as the Rhine Province, a term continuing in the names of the German states of Rhineland-Palatinate and North Rhine-Westphalia.
Following the First World War, the western part of Rhineland was occupied by Entente forces demilitarized under the 1919 Treaty of Versailles and the 1925 Locarno Treaties. German forces remilitarized the territory in 1936, as part of a diplomatic test of will, three years before the outbreak of the Second World War. To the west the area stretches to the borders with Luxembourg and the Netherlands. Stretching down to the North Palatine Uplands in the south, this area, except for the Saarland, more or less corresponds with the modern use of the term; the southern and eastern parts are hill country, cut by river valleys, principally the Middle Rhine up to Bingen and its Ahr and Nahe tributaries. The border of the North German plain is marked by the lower Ruhr. In the south, the river cuts the Rhenish Massif; the area encompasses the western part of the Cologne Lowland. Some of the larger cities in the Rhineland are Aachen, Cologne, Duisburg, Düsseldorf, Koblenz, Leverkusen, Mainz, Mönchengladbach, Mülheim an der Ruhr, Remscheid, Solingen and Wuppertal.
Toponyms as well as local family names trace back to the Frankish heritage. The lands on the western shore of the Rhine are characterized by Roman influence, including viticulture. In the core territories, large parts of the population are members of the Catholic Church. At the earliest historical period, the territories between the Ardennes and the Rhine were occupied by the Treveri, the Eburones and other Celtic tribes, however, were all more or less modified and influenced by their Germanic neighbors. On the East bank of the Rhine, between the Main and the Lahn, were the settlements of the Mattiaci, a branch of the Germanic Chatti, while farther to the north were the Usipetes and Tencteri. Julius Caesar conquered the Celtic tribes on the West bank, Augustus established numerous fortified posts on the Rhine, but the Romans never succeeded in gaining a firm footing on the East bank; as the power of the Roman empire declined the Franks pushed forward along both banks of the Rhine, by the end of the 5th century had conquered all the lands, under Roman influence.
The Frankish conquerors of the Rhenish districts were singularly little affected by the culture of the Roman provincials they subdued, all traces of Roman civilization were submerged. By the 8th century, the Frankish dominion was established in western Germania and northern Gaul. On the division of the Carolingian Empire at the Treaty of Verdun the part the province to the east of the river fell to East Francia, while that to the west remained with the kingdom of Lotharingia. By the time of Emperor Otto I both banks of the Rhine had become part of the Holy Roman Empire, in 959 the Rhenish territory was divided between the duchies of Upper Lorraine, on the Mosel, Lower Lorraine on the Meuse; as the central power of the Holy Roman Emperor weakened, the Rhineland split up into numerous small independent principalities, each with its separate vicissitudes and special chronicles. The old Lotharingian divisions became obsolete, while the Lower Lorraine lands were referred to as the Low Countries, the name of Lorraine became restricted to the region on the upper Moselle that still bears it.
After the Imperial Reform of 1500/12, the territory was part of the Lower Rhenish–Westphalian, Upper Rhenish, Electoral Rhenish Circles. Notable Rhenish Imperial States included: the ecclesiastical electorates of Cologne and Trier the duchies of Jülich and Berg, forming the United Duchies of Jülich-Cleves-Berg from 1521 the County of Sponheim and numerous further Imperial Counties the Free Imperial Cities of Aachen and Cologne. In spite of its dismembered condition and the sufferings it underwent at the hands of its French neighbors in various periods of warfare, the Rhenish territory prospered and stood in the foremost rank of German culture and progress. Aachen was the place of coronation of the German emperors, the ecclesiastical principalities of the Rhine played a large role in German history. At the Peace of Basel in 1795, the whole of the left bank of the Rhine was tak
Berlin is the capital and largest city of Germany by both area and population. Its 3,748,148 inhabitants make it the second most populous city proper of the European Union after London; the city is one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, contiguous with its capital, Potsdam; the two cities are at the center of the Berlin-Brandenburg capital region, which is, with about six million inhabitants and an area of more than 30,000 km², Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the River Spree, which flows into the River Havel in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree and Dahme rivers. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. About one-third of the city's area is composed of forests, gardens, rivers and lakes; the city lies in the Central German dialect area, the Berlin dialect being a variant of the Lusatian-New Marchian dialects.
First documented in the 13th century and situated at the crossing of two important historic trade routes, Berlin became the capital of the Margraviate of Brandenburg, the Kingdom of Prussia, the German Empire, the Weimar Republic, the Third Reich. Berlin in the 1920s was the third largest municipality in the world. After World War II and its subsequent occupation by the victorious countries, the city was divided. East Berlin was declared capital of East Germany. Following German reunification in 1990, Berlin once again became the capital of all of Germany. Berlin is a world city of culture, politics and science, its economy is based on high-tech firms and the service sector, encompassing a diverse range of creative industries, research facilities, media corporations and convention venues. Berlin serves as a continental hub for air and rail traffic and has a complex public transportation network; the metropolis is a popular tourist destination. Significant industries include IT, biomedical engineering, clean tech, biotechnology and electronics.
Berlin is home to world-renowned universities, orchestras and entertainment venues, is host to many sporting events. Its Zoological Garden is one of the most popular worldwide. With the world's oldest large-scale movie studio complex, Berlin is an popular location for international film productions; the city is well known for its festivals, diverse architecture, contemporary arts and a high quality of living. Since the 2000s Berlin has seen the emergence of a cosmopolitan entrepreneurial scene. Berlin lies in northeastern Germany, east of the River Saale, that once constituted, together with the River Elbe, the eastern border of the Frankish Realm. While the Frankish Realm was inhabited by Germanic tribes like the Franks and the Saxons, the regions east of the border rivers were inhabited by Slavic tribes; this is why most of the villages in northeastern Germany bear Slavic-derived names. Typical Germanised place name suffixes of Slavic origin are -ow, -itz, -vitz, -witz, -itzsch and -in, prefixes are Windisch and Wendisch.
The name Berlin has its roots in the language of West Slavic inhabitants of the area of today's Berlin, may be related to the Old Polabian stem berl-/birl-. Since the Ber- at the beginning sounds like the German word Bär, a bear appears in the coat of arms of the city, it is therefore a canting arm. Of Berlin's twelve boroughs, five bear a Slavic-derived name: Pankow, Steglitz-Zehlendorf, Marzahn-Hellersdorf, Treptow-Köpenick and Spandau. Of its ninety-six neighborhoods, twenty-two bear a Slavic-derived name: Altglienicke, Alt-Treptow, Buch, Gatow, Kladow, Köpenick, Lankwitz, Lübars, Marzahn, Prenzlauer Berg, Schmöckwitz, Stadtrandsiedlung Malchow, Steglitz and Zehlendorf; the neighborhood of Moabit bears a French-derived name, Französisch Buchholz is named after the Huguenots. The earliest evidence of settlements in the area of today's Berlin are a wooden beam dated from 1192, remnants of a house foundation dated to 1174, found in excavations in Berlin Mitte; the first written records of towns in the area of present-day Berlin date from the late 12th century.
Spandau is first mentioned in 1197 and Köpenick in 1209, although these areas did not join Berlin until 1920. The central part of Berlin can be traced back to two towns. Cölln on the Fischerinsel is first mentioned in a 1237 document, Berlin, across the Spree in what is now called the Nikolaiviertel, is referenced in a document from 1244. 1237 is considered the founding date of the city. The two towns over time formed close economic and social ties, profited from the staple right on the two important trade routes Via Imperii and from Bruges to Novgorod. In 1307, they formed an alliance with a common external policy, their internal administrations still being separated. In 1415, Frederick I became the elector of the Margraviate of Brandenburg, which he ruled until 1440. During the 15th century, his successors established Berlin-Cölln as capital of the margraviate, subsequent members of the Hohenzol
Air draft is the distance from the surface of the water to the highest point on a vessel. This is similar to the "deep draft" of a vessel, measured from the surface of the water to the deepest part of the hull below the surface, but air draft is expressed as a height, not a depth; the vessel's "clearance" is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc. A bridge's "clearance below" is most noted on charts as measured from the surface of the water to the under side of the bridge at Mean Highest High Water, the most restrictive clearance; the height of the tide at any time below its highest point at MHHW will increase the clearance under the bridge. In 2014, the United States Coast Guard reported that 1.2% of the collisions it investigated in the recent past were due to vessels attempting to pass underneath structures with insufficient clearance. At several bridges, such as the Gerald Desmond Bridge in Long Beach, California, NOAA has installed an "Air Gap" measuring device that measures the distance from its sensor on the bridge to the water surface and can be accessed by marine pilots and ship's masters to aid them in making real time determination of clearance.
The Bridge of the Americas in Panama limits which ships can traverse the Panama Canal due to its height at 61.3 m above the water. The world's largest cruise ships, Oasis of the Seas, Allure of the Seas and the Harmony of the Seas will fit within the canal's new widened locks, but they are too tall to pass under the Bridge of the Americas at low tide, unless the Bridge of the Americas is raised or replaced in the future. New ships are built not clearing 65 m; the Suez Canal Bridge has a 70-metre clearance over the canal, 8.7 m higher than Panama. The Bayonne Bridge is an arch bridge connecting New Jersey with New York City, the roadbed was raised to 66 m, a height suitable for larger container ships to pass, the modification cost $1.32 billion.

The German reunification was the process in 1990 in which the German Democratic Republic became part of the Federal Republic of Germany to form the reunited nation of Germany, when Berlin reunited into a single city, as provided by its Grundgesetz Article 23. The end of the unification process is referred to as German unity, celebrated on 3 October. Following German reunification, Berlin was once again designated as the capital of united Germany; the East German government started to falter in May 1989, when the removal of Hungary's border fence with Austria opened a hole in the Iron Curtain. It caused an exodus of thousands of East Germans fleeing to West Austria via Hungary; the Peaceful Revolution, a series of protests by East Germans, led to the GDR's first free elections on 18 March 1990, to the negotiations between the GDR and FRG that culminated in a Unification Treaty. Other negotiations between the GDR and FRG and the four occupying powers produced the so-called "Two Plus Four Treaty" granting full sovereignty to a unified German state, whose two parts were bound by a number of limitations stemming from their post-World War II status as occupied regions.
The 1945 Potsdam Agreement had specified that a full peace treaty concluding World War II, including the exact delimitation of Germany's postwar boundaries, required to be "accepted by the Government of Germany when a government adequate for the purpose is established." The Federal Republic had always maintained that no such government could be said to have been established until East and West Germany had been united within a free democratic state. The key question was whether a Germany that remained bounded to the east by the Oder–Neisse line could act as a "united Germany" in signing the peace treaty without qualification. Under the "Two Plus Four Treaty" both the Federal Republic and the Democratic Republic committed themselves and their unified continuation to the principle that their joint pre-1990 boundaries constituted the entire territory that could be claimed by a Government of Germany, hence that there were no further lands outside those boundaries that were parts of Germany as a whole.
The united Germany is not a successor state, but an enlarged continuation of the former West Germany. As such, the enlarged Federal Republic of Germany retained the West German seats in international organizations including the European Community and NATO, while relinquishing membership in the Warsaw Pact and other international organizations to which only East Germany belonged, it maintains the United Nations membership of the old West Germany. For political and diplomatic reasons, West German politicians avoided the term "reunification" during the run-up to what Germans refer to as die Wende; the official and most common term in German is "Deutsche Einheit". After 1990, the term "die Wende" became more common; the term refers to the events that led up to the actual reunification. When referring to the events surrounding reunification, however, it carries the cultural connotation of the time and the events in the GDR that brought about this "turnaround" in German history. However, anti-communist activists from Eastern Germany rejected the term Wende as it was introduced by SED's Secretary General Egon Krenz.
In 1945, the Third Reich ended in defeat and Germany was divided into four occupation zones, under the Soviet Union, the United States, the United Kingdom, France. The capital city of Berlin was divided into four sectors. Between 1947 and 1949, the three zones of the western allies were merged, forming the Federal Republic of Germany and West Berlin, aligned with capitalist Europe; the Soviet zone became the German Democratic Republic with its capital in East Berlin, part of the communist Soviet Bloc. The FRG was a member of the western military alliance, NATO and the GDR was a member of the Warsaw Pact. Germans lived under such imposed divisions throughout the ensuing Cold War. Into the 1980s, the Soviet Union experienced a period of economic and political stagnation, correspondingly decreased intervention in Eastern Bloc politics. In 1987, US President Ronald Reagan gave a speech at the Brandenburg Gate, challenging Soviet leader Mikhail Gorbachev to "tear down the wall" which divided Berlin.
The wall had stood as an icon for the political and economic division between East and West, a division that Churchill had referred to as the "Iron Curtain". Gorbachev announced in 1988 that the Soviet Union would abandon the Brezhnev Doctrine and allow the Eastern bloc nations to determine their own internal affairs. In early 1989, under a new era of Soviet policies of glasnost and taken further by Gorbachev, the Solidarity movement took hold in Poland. Further inspired by other images of brave defiance, a wave
Steel is an alloy of iron and carbon, sometimes other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, tools, automobiles, machines and weapons. Iron is the base metal of steel. Iron is able to take on two crystalline forms, body centered cubic and face centered cubic, depending on its temperature. In the body-centered cubic arrangement, there is an iron atom in the center and eight atoms at the vertices of each cubic unit cell, it is the interaction of the allotropes of iron with the alloying elements carbon, that gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has little resistance to the iron atoms slipping past one another, so pure iron is quite ductile, or soft and formed. In steel, small amounts of carbon, other elements, inclusions within the iron act as hardening agents that prevent the movement of dislocations that are common in the crystal lattices of iron atoms; the carbon in typical steel alloys may contribute up to 2.14% of its weight.
Varying the amount of carbon and many other alloying elements, as well as controlling their chemical and physical makeup in the final steel, slows the movement of those dislocations that make pure iron ductile, thus controls and enhances its qualities. These qualities include such things as the hardness, quenching behavior, need for annealing, tempering behavior, yield strength, tensile strength of the resulting steel; the increase in steel's strength compared to pure iron is possible only by reducing iron's ductility. Steel was produced in bloomery furnaces for thousands of years, but its large-scale, industrial use began only after more efficient production methods were devised in the 17th century, with the production of blister steel and crucible steel. With the invention of the Bessemer process in the mid-19th century, a new era of mass-produced steel began; this was followed by the Siemens–Martin process and the Gilchrist–Thomas process that refined the quality of steel. With their introductions, mild steel replaced wrought iron.
Further refinements in the process, such as basic oxygen steelmaking replaced earlier methods by further lowering the cost of production and increasing the quality of the final product. Today, steel is one of the most common manmade materials in the world, with more than 1.6 billion tons produced annually. Modern steel is identified by various grades defined by assorted standards organizations; the noun steel originates from the Proto-Germanic adjective stahliją or stakhlijan, related to stahlaz or stahliją. The carbon content of steel is between 0.002% and 2.14% by weight for plain iron–carbon alloys. These values vary depending on alloying elements such as manganese, nickel, so on. Steel is an iron-carbon alloy that does not undergo eutectic reaction. In contrast, cast iron does undergo eutectic reaction. Too little carbon content leaves iron quite soft and weak. Carbon contents higher than those of steel make a brittle alloy called pig iron. While iron alloyed with carbon is called carbon steel, alloy steel is steel to which other alloying elements have been intentionally added to modify the characteristics of steel.
Common alloying elements include: manganese, chromium, boron, vanadium, tungsten and niobium. Additional elements, most considered undesirable, are important in steel: phosphorus, sulfur and traces of oxygen and copper. Plain carbon-iron alloys with a higher than 2.1% carbon content are known as cast iron. With modern steelmaking techniques such as powder metal forming, it is possible to make high-carbon steels, but such are not common. Cast iron is not malleable when hot, but it can be formed by casting as it has a lower melting point than steel and good castability properties. Certain compositions of cast iron, while retaining the economies of melting and casting, can be heat treated after casting to make malleable iron or ductile iron objects. Steel is distinguishable from wrought iron, which may contain a small amount of carbon but large amounts of slag. Iron is found in the Earth's crust in the form of an ore an iron oxide, such as magnetite or hematite. Iron is extracted from iron ore by removing the oxygen through its combination with a preferred chemical partner such as carbon, lost to the atmosphere as carbon dioxide.
This process, known as smelting, was first applied to metals with lower melting points, such as tin, which melts at about 250 °C, copper, which melts at about 1,100 °C, the combination, which has a melting point lower than 1,083 °C. In comparison, cast iron melts at about 1,375 °C. Small quantities of iron were smelted in ancient times, in the solid state, by heating the ore in a charcoal fire and welding the clumps together with a hammer and in the process squeezing out the impurities. With care, the carbon content could be controlled by moving it around in the fire. Unlike copper and tin, liquid or solid iron dissolves carbon quite readily. All of these temperatures could be reached with ancient methods used since the Bronze Age. Since the oxidation rate of iron increases beyond 800 °C, it is important that smelting take place in a low-oxygen environment. Smelting, using carbon to reduce iro
Hanna is a 2011 action-adventure thriller film directed by Joe Wright. The film stars Saoirse Ronan as the title character, a girl raised in the wilderness of northern Finland by her father, an ex-CIA operative, who trains her as an assassin. Cate Blanchett portrays a senior CIA agent who tries to track down and eliminate the girl and her father; the soundtrack was written by The Chemical Brothers. Hanna was released in North America in April 2011 and in Europe in May 2011; the film received a positive response from most critics, with reviewers praising the performances of Ronan and Blanchett as well as the action sequences and themes. Hanna Heller is a fifteen-year-old girl who lives with Erik, in rural northern Finland. Since the age of two, Hanna has been trained by Erik, an ex-CIA operative from Germany, to be a skilled assassin, he drills her in target shooting. Erik knows a secret that cannot become public, Marissa Wiegler, a senior CIA officer, searches for him in order to eliminate him.
Erik has trained Hanna with the intent. One night, Hanna tells Erik. Erik digs up a radio beacon that will alert the CIA to their presence. Although he warns Hanna that a confrontation with Marissa will be fatal for either her or Marissa, he leaves the final decision to Hanna, who activates the beacon. Erik leaves. Hanna is taken to an underground CIA complex in Morocco where a suspicious Marissa sends a body double. While talking to the double, Hanna starts to cry and crawls sobbing into the lap of the double, which makes her captors uneasy, they send. As they enter the cell, Hanna escapes. Hanna meets Sebastian and Rachel, who are on a camper-van holiday with their children and Miles, in Morocco, she stows away in the family's camper-van on the ferry ride to Spain, seeking to reach Berlin. The family is kind to her, she and Sophie become friends sharing a kiss. Marissa hires a sadistic former agent, to capture Hanna. Hanna travels with the family. Isaacs and two skinheads trail them and corner Hanna and the family near Hamburg, but she manages to escape, killing one of the assailants.
Marissa catches up with the British family and during interrogation finds out that Hanna is heading to Berlin. Arriving at the address that Erik had given her, Hanna meets with Knepfler, an eccentric old magician and a friend of Erik's, who lives in an abandoned amusement park. Hanna plans a rendezvous with her father; however and Isaacs arrive. Hanna overhears comments that suggest Erik is not her biological father. Hanna goes to her grandmother's apartment where she finds Erik, who has unsuccessfully tried to kill Marissa in her hotel room. Hanna's grandmother has been murdered by Marissa. Erik admits, he once recruited pregnant women into a CIA program where their children's DNA was enhanced in order to create super-soldiers. After the project was shut down, its subjects were eliminated. Marissa and Isaacs arrive. Erik is shot by Marissa, who goes to Knepfler's house. Hanna is there. After a chase, Hanna kills Marissa; the film's story and script were written by Seth Lochhead while a student at Vancouver Film School.
He wrote the original story and script on spec, finalized the script in 2006, with David Farr providing changes. Danny Boyle and Alfonso Cuarón were attached to direct the film, before it was confirmed that Joe Wright would direct, after Ronan prompted the producers to consider him; the film was co-produced by the American Holleran Company and German Studio Babelsberg, with financial support from various German film funds and the main distributor, Focus Features, which holds the copyright to the film. Most of the filming was done at Studio Babelsberg in Berlin, but locations included Lake Kitka in Kuusamo, several German locations, as well as Ouarzazate and Essaouira in Morocco. Temperatures during the Finland shoot sometimes fell as low as −33 °C, but Ronan said "Finland did bring out the fairy tale aspects of the story. We were shooting on a frozen lake, surrounded by pine trees covered in snow". Reviewers remarked that the setting and style of Hanna depart from a typical action movie. According to the official website, the film has "elements of dark fairy tales" woven into an "adventure thriller".
Joe Wright, the director, has said that the movie's theme is a "fantasy" about "overcoming the dark side" during the "rites of passage" of adolescent maturation when a child transforms and "has to go into the world". He said that he was influenced by personal exposure every day as he grew up to "violent, cautionary fairy tales" that "prepare children for the future obstacles in the wider world", as well as his "deep love for the mystical qualities of David Lynch movies", by the patterns of narrative that he prefers because of his dyslexia, by working as a child in his parents' puppetry company. In an interview with Film School Rejects, Wright acknowledged David Lynch as a major influence on Hanna and pointed to The Chemical Brothers' score: "You can expect an extraordinarily loud, thumping funky score that will not disappoint"; the music, including The Devil Is In The Beats and The Devil Is In The Details
