Galata Tower
–
One of the citys most striking landmarks, it is a high, cone-capped cylinder that dominates the skyline and offers a panoramic vista of Istanbuls historic peninsula and its environs. The nine-story tower is 66.90 m, and was the citys tallest structure when it was built, the elevation at ground level is 35 m above sea-level. The tower has an diameter of 16.45 m at the base, an inside diameter of 8.95 m. There is a restaurant and café on its upper floors which command a magnificent view of Istanbul, also located on the upper floors is a night club which hosts a Turkish show. There are two operating elevators that carry visitors from the level to the upper levels. The Romanesque style tower was built as Christea Turris in 1348 during an expansion of the Genoese colony in Constantinople, Galata Tower was the tallest building in Istanbul at 219.5 ft when it was built in 1348. That tower was on a different site and was destroyed in 1203. The upper section of the tower with the cap was slightly modified in several restorations during the Ottoman period when it was used as an observation tower for spotting fires. Evliyâ Çelebi also tells of Hezarfens brother, Lagari Hasan Çelebi, starting from 1717, the Ottomans began to use the tower for spotting fires in the city. In 1794, during the reign of Sultan Selim III, the roof of the tower was made of lead and wood, another fire damaged the building in 1831, upon which a new restoration work took place. In 1875, during a storm, the roof on the top of the building was destroyed. The tower remained without this conical roof for the rest of the Ottoman period, many years later, during the restoration works between 1965 and 1967, the conical roof was reconstructed. During this final restoration in the 1960s, the interior of the tower was replaced by a concrete structure. From the top of the tower, the first French panorama painter, Pierre Prévost, drew his Panorama de Constantinople in 1818, which was later exhibited in Paris in 1825. The panorama image shown below is composed of ten photos taken from the Galata Tower by the firm of Sébah & Joaillier.

Istanbul
–
Istanbul, historically known as Constantinople and Byzantium, is the most populous city in Turkey and the countrys economic, cultural, and historic center. Istanbul is a city in Eurasia, straddling the Bosphorus strait between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives on the Asian side, the city is the administrative center of the Istanbul Metropolitan Municipality, both hosting a population of around 14.7 million residents. Istanbul is one of the worlds most populous cities and ranks as the worlds 7th-largest city proper, founded under the name of Byzantion on the Sarayburnu promontory around 660 BCE, the city developed to become one of the most significant in history. After its reestablishment as Constantinople in 330 CE, it served as a capital for almost 16 centuries, during the Roman and Byzantine, the Latin. Overlooked for the new capital Ankara during the period, the city has since regained much of its prominence. The population of the city has increased tenfold since the 1950s, as migrants from across Anatolia have moved in, arts, music, film, and cultural festivals were established at the end of the 20th century and continue to be hosted by the city today. Infrastructure improvements have produced a complex transportation network, considered a global city, Istanbul has one of the fastest-growing metropolitan economies in the world. It hosts the headquarters of many Turkish companies and media outlets and accounts for more than a quarter of the gross domestic product. Hoping to capitalize on its revitalization and rapid expansion, Istanbul has bid for the Summer Olympics five times in twenty years, the first known name of the city is Byzantium, the name given to it at its foundation by Megarean colonists around 660 BCE. The name is thought to be derived from a personal name, ancient Greek tradition refers to a legendary king of that name as the leader of the Greek colonists. Modern scholars have hypothesized that the name of Byzas was of local Thracian or Illyrian origin. He also attempted to promote the name Nova Roma and its Greek version Νέα Ῥώμη Nea Romē, the use of Constantinople to refer to the city during the Ottoman period is now considered politically incorrect, even if not historically inaccurate, by Turks. By the 19th century, the city had acquired other names used by foreigners or Turks. Europeans used Constantinople to refer to the whole of the city, pera was used to describe the area between the Golden Horn and the Bosphorus, but Turks also used the name Beyoğlu. The name İstanbul is commonly held to derive from the Medieval Greek phrase εἰς τὴν Πόλιν and this reflected its status as the only major city in the vicinity. The importance of Constantinople in the Ottoman world was reflected by its Ottoman name Der Saadet meaning the gate to Prosperity in Ottoman. An alternative view is that the name evolved directly from the name Constantinople, with the first, a Turkish folk etymology traces the name to Islam bol plenty of Islam because the city was called Islambol or Islambul as the capital of the Islamic Ottoman Empire

Concrete
–
Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement that hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, when aggregate is mixed together with dry Portland cement and water, the mixture forms a fluid slurry that is easily poured and molded into shape. The cement reacts chemically with the water and other ingredients to form a matrix that binds the materials together into a durable stone-like material that has many uses. Often, additives are included in the mixture to improve the properties of the wet mix or the finished material. Most concrete is poured with reinforcing materials embedded to provide tensile strength, famous concrete structures include the Hoover Dam, the Panama Canal, and the Roman Pantheon. The earliest large-scale users of technology were the ancient Romans. The Colosseum in Rome was built largely of concrete, and the dome of the Pantheon is the worlds largest unreinforced concrete dome. Today, large concrete structures are made with reinforced concrete. After the Roman Empire collapsed, use of concrete became rare until the technology was redeveloped in the mid-18th century, today, concrete is the most widely used man-made material. The word concrete comes from the Latin word concretus, the passive participle of concrescere, from con-. Perhaps the earliest known occurrence of cement was twelve years ago. A deposit of cement was formed after an occurrence of oil shale located adjacent to a bed of limestone burned due to natural causes and these ancient deposits were investigated in the 1960s and 1970s. On a human timescale, small usages of concrete go back for thousands of years and they discovered the advantages of hydraulic lime, with some self-cementing properties, by 700 BC. They built kilns to supply mortar for the construction of houses, concrete floors. The cisterns were kept secret and were one of the reasons the Nabataea were able to thrive in the desert, some of these structures survive to this day. In the Ancient Egyptian and later Roman eras, it was re-discovered that adding volcanic ash to the mix allowed it to set underwater, similarly, the Romans knew that adding horse hair made concrete less liable to crack while it hardened, and adding blood made it more frost-resistant. Crystallization of strätlingite and the introduction of pyroclastic clays creates further fracture resistance, german archaeologist Heinrich Schliemann found concrete floors, which were made of lime and pebbles, in the royal palace of Tiryns, Greece, which dates roughly to 1400–1200 BC. Lime mortars were used in Greece, Crete, and Cyprus in 800 BC, the Assyrian Jerwan Aqueduct made use of waterproof concrete

Turkey
–
Turkey, officially the Republic of Turkey, is a transcontinental country in Eurasia, mainly in Anatolia in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is a democratic, secular, unitary, parliamentary republic with a cultural heritage. The country is encircled by seas on three sides, the Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, Ankara is the capital while Istanbul is the countrys largest city and main cultural and commercial centre. Approximately 70-80% of the countrys citizens identify themselves as ethnic Turks, other ethnic groups include legally recognised and unrecognised minorities. Kurds are the largest ethnic minority group, making up approximately 20% of the population, the area of Turkey has been inhabited since the Paleolithic by various ancient Anatolian civilisations, as well as Assyrians, Greeks, Thracians, Phrygians, Urartians and Armenians. After Alexander the Greats conquest, the area was Hellenized, a process continued under the Roman Empire. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, the empire reached the peak of its power in the 16th century, especially during the reign of Suleiman the Magnificent. During the war, the Ottoman government committed genocides against its Armenian, Assyrian, following the war, the conglomeration of territories and peoples that formerly comprised the Ottoman Empire was partitioned into several new states. Turkey is a member of the UN, an early member of NATO. Turkeys growing economy and diplomatic initiatives have led to its recognition as a regional power while her location has given it geopolitical, the name of Turkey is based on the ethnonym Türk. The first recorded use of the term Türk or Türük as an autonym is contained in the Old Turkic inscriptions of the Göktürks of Central Asia, the English name Turkey first appeared in the late 14th century and is derived from Medieval Latin Turchia. Similarly, the medieval Khazar Empire, a Turkic state on the shores of the Black. The medieval Arabs referred to the Mamluk Sultanate as al-Dawla al-Turkiyya, the Ottoman Empire was sometimes referred to as Turkey or the Turkish Empire among its European contemporaries. The Anatolian peninsula, comprising most of modern Turkey, is one of the oldest permanently settled regions in the world, various ancient Anatolian populations have lived in Anatolia, from at least the Neolithic period until the Hellenistic period. Many of these peoples spoke the Anatolian languages, a branch of the larger Indo-European language family, in fact, given the antiquity of the Indo-European Hittite and Luwian languages, some scholars have proposed Anatolia as the hypothetical centre from which the Indo-European languages radiated. The European part of Turkey, called Eastern Thrace, has also been inhabited since at least forty years ago. It is the largest and best-preserved Neolithic site found to date, the settlement of Troy started in the Neolithic Age and continued into the Iron Age

Turkish literature
–
The Ottoman and Azeri forms of Turkish, which forms the basis of much of the written corpus, are highly influenced by Persian and Arabic literature, and used the Ottoman Turkish alphabet. The history of the broader Turkic literature spans a period of nearly 1,300 years, the oldest extant records of written Turkic are the Orhon inscriptions, found in the Orhon River valley in central Mongolia and dating to the 7th century. For the next 900 years, until shortly before the fall of the Ottoman Empire in 1922, with the founding of the Republic of Turkey in 1923, the two traditions came together for the first time. Throughout most of its history, Turkish literature has been sharply divided into two different traditions, neither of which exercised much influence upon the other until the 19th century. The first of two traditions is Turkish folk literature, and the second is Turkish written literature. For most of the history of Turkish literature, the salient difference between the folk and the written traditions has been the variety of language employed. The folk tradition, by and large, was oral and remained free of the influence of Persian and Arabic literature, when the Ottoman Empire arose early in the 14th century, in northwestern Anatolia, it continued this tradition. Out of this confluence of choices, the Ottoman Turkish language—which was always distinct from standard Turkish—was effectively born. This style of writing under Persian and Arabic influence came to be known as Divan literature, Turkish folk literature is an oral tradition deeply rooted, in its form, in Central Asian nomadic traditions. However, in its themes, Turkish folk literature reflects the problems peculiar to a people who have abandoned the nomadic lifestyle. Another example is the mysterious figure of Nasreddin, a trickster who often plays jokes, of a sort. The religion henceforth came to exercise an influence on Turkish society and literature, particularly the heavily mystically oriented Sufi. The word aşık is in fact the term used for members of the Bektashi order. There are three basic genres in the tradition, epic, folk poetry, and folklore, the Book of Dede Korkut endured in the oral tradition of the Oghuz Turks after settling in Anatolia. Alpamysh is an epic, still preserved in the literature of various Turkic peoples of Central Asia in addition to its important place in the Anatolian tradition. The Book of Dede Korkut was the element of the Azerbaijani–Turkish epic tradition in the Caucasus. Concurrent to the Book of Dede Korkut was the so-called Epic of Köroğlu, complicating matters somewhat is the fact that Köroğlu is also the name of a poet of the aşık/ozan tradition. The epic tradition in modern Turkish literature may be seen in the Epic of Shaykh Bedreddin, many of the works of the 20th-century novelist Yaşar Kemal, such as the 1955 novel Memed, My Hawk, can be considered modern prose epics continuing this long tradition

Justinian I
–
Justinian I, traditionally known as Justinian the Great and also Saint Justinian the Great in the Eastern Orthodox Church, was a Byzantine emperor from 527 to 565. During his reign, Justinian sought to revive the empires greatness, because of his restoration activities, Justinian has sometimes been called the last Roman in modern historiography. This ambition was expressed by the recovery of the territories of the defunct western Roman Empire. His general, Belisarius, swiftly conquered the Vandal kingdom in North Africa, the prefect Liberius reclaimed the south of the Iberian peninsula, establishing the province of Spania. These campaigns re-established Roman control over the western Mediterranean, increasing the Empires annual revenue by over a million solidi, during his reign Justinian also subdued the Tzani, a people on the east coast of the Black Sea that had never been under Roman rule before. A still more resonant aspect of his legacy was the rewriting of Roman law, the Corpus Juris Civilis. His reign also marked a blossoming of Byzantine culture, and his building program yielded such masterpieces as the church of Hagia Sophia, a devastating outbreak of bubonic plague in the early 540s marked the end of an age of splendour. Justinian was born in Tauresium around 482, a native speaker of Latin, he came from a peasant family believed to have been of Illyro-Roman or Thraco-Roman origins. The cognomen Iustinianus, which he later, is indicative of adoption by his uncle Justin. During his reign, he founded Justiniana Prima not far from his birthplace and his mother was Vigilantia, the sister of Justin. Justin, who was in the guard before he became emperor, adopted Justinian, brought him to Constantinople. As a result, Justinian was well educated in jurisprudence, theology, Justinian served for some time with the Excubitors but the details of his early career are unknown. Chronicler John Malalas, who lived during the reign of Justinian, tells of his appearance that he was short, fair skinned, curly haired, round faced, another contemporary chronicler, Procopius, compares Justinians appearance to that of tyrannical Emperor Domitian, although this is probably slander. When Emperor Anastasius died in 518, Justin was proclaimed the new emperor, during Justins reign, Justinian was the emperors close confidant. As Justin became senile near the end of his reign, Justinian became the de facto ruler, Justinian was appointed consul in 521 and later commander of the army of the east. Upon Justins death on 1 August 527, Justinian became the sole sovereign, as a ruler, Justinian showed great energy. He was known as the emperor who never sleeps on account of his work habits, nevertheless, he seems to have been amiable and easy to approach. Around 525, he married his mistress, Theodora, in Constantinople and she was by profession a courtesan and some twenty years his junior

Walls of Constantinople
–
With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. Initially built by Constantine the Great, the walls surrounded the new city on all sides, as the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Ultimately the city fell from sheer weight of numbers of the Ottoman forces on 29 May 1453 after a six-week siege. The walls were largely maintained intact during most of the Ottoman period, until sections began to be dismantled in the 19th century, despite the subsequent lack of maintenance, many parts of the walls survived and are still standing today. A large-scale restoration program has been under way since the 1980s, according to tradition, the city was founded as Byzantium by Greek colonists from Megara, led by the eponymous Byzas, around 658 BC. At the time the city consisted of a region around an acropolis. This wall was protected by 27 towers, and had at least two gates, one which survived to become known as the Arch of Urbicius. On the seaward side, the wall was much lower and this wall is known to have been repaired, utilising tomb stones, under the leadership of a certain Leo in 340 BC, against an attack by Philip II of Macedon. Byzantium was relatively unimportant during the early Roman period, contemporaries described it as wealthy, well peopled and well fortified, but this affluence came to an end due to its support for Pescennius Niger in his war against Septimius Severus. Severus punished the city harshly, the walls were demolished. The Patria also mention the existence of another wall during the siege of Byzantium by Constantine the Great during the conflict with Licinius. Like Severus before him, Constantine began to punish the city for siding with his defeated rival, during 324–336 the city was thoroughly rebuilt and inaugurated on 11 May 330 under the name of Second Rome. The name that prevailed in common usage however was Constantinople. The city of Constantine was protected by a new wall about 2.8 km west of the Severan wall, constantines fortification consisted of a single wall, reinforced with towers at regular distances, which began to be constructed in 324 and was completed under his son Constantius II. Only the approximate course of the wall is known, it began at the Church of St. Aemilianus, already by the early 5th century however, Constantinople had expanded outside the Constantinian Wall, in the extramural area known as the Exokionion or Exakionion. The wall survived during much of the Byzantine period, even though it was replaced by the Theodosian Walls as the primary defence. Only traces of the wall appear to have survived in later ages, the recent construction of Yenikapı Transfer Center has unearthed a section of the foundation of the wall of Constantine. The names of a number of gates of the Constantinian Wall survive, the gate stood somewhere on the southern slopes of the Seventh Hill

Ottoman Empire
–
After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror, at the beginning of the 17th century the empire contained 32 provinces and numerous vassal states. Some of these were later absorbed into the Ottoman Empire, while others were granted various types of autonomy during the course of centuries. With Constantinople as its capital and control of lands around the Mediterranean basin, while the empire was once thought to have entered a period of decline following the death of Suleiman the Magnificent, this view is no longer supported by the majority of academic historians. The empire continued to maintain a flexible and strong economy, society, however, during a long period of peace from 1740 to 1768, the Ottoman military system fell behind that of their European rivals, the Habsburg and Russian Empires. While the Empire was able to hold its own during the conflict, it was struggling with internal dissent. Starting before World War I, but growing increasingly common and violent during it, major atrocities were committed by the Ottoman government against the Armenians, Assyrians and Pontic Greeks. The word Ottoman is an anglicisation of the name of Osman I. Osmans name in turn was the Turkish form of the Arabic name ʿUthmān, in Ottoman Turkish, the empire was referred to as Devlet-i ʿAlīye-yi ʿOsmānīye, or alternatively ʿOsmānlı Devleti. In Modern Turkish, it is known as Osmanlı İmparatorluğu or Osmanlı Devleti, the Turkish word for Ottoman originally referred to the tribal followers of Osman in the fourteenth century, and subsequently came to be used to refer to the empires military-administrative elite. In contrast, the term Turk was used to refer to the Anatolian peasant and tribal population, the term Rūmī was also used to refer to Turkish-speakers by the other Muslim peoples of the empire and beyond. In Western Europe, the two names Ottoman Empire and Turkey were often used interchangeably, with Turkey being increasingly favored both in formal and informal situations and this dichotomy was officially ended in 1920–23, when the newly established Ankara-based Turkish government chose Turkey as the sole official name. Most scholarly historians avoid the terms Turkey, Turks, and Turkish when referring to the Ottomans, as the power of the Seljuk Sultanate of Rum declined in the 13th century, Anatolia was divided into a patchwork of independent Turkish principalities known as the Anatolian Beyliks. One of these beyliks, in the region of Bithynia on the frontier of the Byzantine Empire, was led by the Turkish tribal leader Osman, osmans early followers consisted both of Turkish tribal groups and Byzantine renegades, many but not all converts to Islam. Osman extended the control of his principality by conquering Byzantine towns along the Sakarya River and it is not well understood how the early Ottomans came to dominate their neighbours, due to the scarcity of the sources which survive from this period. One school of thought which was popular during the twentieth century argued that the Ottomans achieved success by rallying religious warriors to fight for them in the name of Islam, in the century after the death of Osman I, Ottoman rule began to extend over Anatolia and the Balkans. Osmans son, Orhan, captured the northwestern Anatolian city of Bursa in 1326 and this conquest meant the loss of Byzantine control over northwestern Anatolia. The important city of Thessaloniki was captured from the Venetians in 1387, the Ottoman victory at Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe

Leonardo da Vinci
–
He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time. Sometimes credited with the inventions of the parachute, helicopter and tank, many historians and scholars regard Leonardo as the prime exemplar of the Universal Genius or Renaissance Man, an individual of unquenchable curiosity and feverishly inventive imagination. Much of his working life was spent in the service of Ludovico il Moro in Milan. He later worked in Rome, Bologna and Venice, and he spent his last years in France at the home awarded to him by Francis I of France, Leonardo was, and is, renowned primarily as a painter. Among his works, the Mona Lisa is the most famous and most parodied portrait, Leonardos drawing of the Vitruvian Man is also regarded as a cultural icon, being reproduced on items as varied as the euro coin, textbooks, and T-shirts. Perhaps fifteen of his paintings have survived, Leonardo is revered for his technological ingenuity. He conceptualised flying machines, a type of armoured fighting vehicle, concentrated power, an adding machine. Some of his inventions, however, such as an automated bobbin winder. A number of Leonardos most practical inventions are nowadays displayed as working models at the Museum of Vinci. He made substantial discoveries in anatomy, civil engineering, geology, optics, and hydrodynamics, today, Leonardo is widely considered one of the most diversely talented individuals ever to have lived. Leonardo was born on 15 April 1452 at the hour of the night in the Tuscan hill town of Vinci. He was the son of the wealthy Messer Piero Fruosino di Antonio da Vinci, a Florentine legal notary, and Caterina. Leonardo had no surname in the modern sense – da Vinci simply meaning of Vinci, his birth name was Lionardo di ser Piero da Vinci, meaning Leonardo. The inclusion of the title ser indicated that Leonardos father was a gentleman, little is known about Leonardos early life. He spent his first five years in the hamlet of Anchiano in the home of his mother and his father had married a sixteen-year-old girl named Albiera Amadori, who loved Leonardo but died young in 1465 without children. When Leonardo was sixteen, his father married again to twenty-year-old Francesca Lanfredini, pieros legitimate heirs were born from his third wife Margherita di Guglielmo and his fourth and final wife, Lucrezia Cortigiani. Leonardo received an education in Latin, geometry and mathematics. In later life, Leonardo recorded only two childhood incidents, one, which he regarded as an omen, was when a kite dropped from the sky and hovered over his cradle, its tail feathers brushing his face
