Castle
–
A castle is a type of fortified structure built in Europe and the Middle East during the Middle Ages by European nobility. Scholars debate the scope of the castle, but usually consider it to be the private fortified residence of a lord or noble. Usage of the term has varied over time and has applied to structures as diverse as hill forts. Over the approximately 900 years that castles were built, they took on a great many forms with different features, although some, such as curtain walls. A European innovation, castles originated in the 9th and 10th centuries, after the fall of the Carolingian Empire resulted in its territory being divided among individual lords and princes. Although their military origins are often emphasised in castle studies, the structures served as centres of administration. Many castles were built from earth and timber, but had their defences replaced later by stone. Early castles often exploited natural defences, lacking features such as towers and arrowslits, in the late 12th and early 13th centuries, a scientific approach to castle defence emerged. This led to the proliferation of towers, with an emphasis on flanking fire, many new castles were polygonal or relied on concentric defence – several stages of defence within each other that could all function at the same time to maximise the castles firepower. These changes in defence have been attributed to a mixture of castle technology from the Crusades, such as concentric fortification, not all the elements of castle architecture were military in nature, so that devices such as moats evolved from their original purpose of defence into symbols of power. Some grand castles had long winding approaches intended to impress and dominate their landscape, while castles continued to be built well into the 16th century, new techniques to deal with improved cannon fire made them uncomfortable and undesirable places to live. As a result, true castles went into decline and were replaced by artillery forts with no role in civil administration, and country houses that were indefensible. From the 18th century onwards, there was a renewed interest in castles with the construction of castles, part of a romantic revival of Gothic architecture. The word castle is derived from the Latin word castellum, which is a diminutive of the word castrum, meaning fortified place. The Old English castel, Old French castel or chastel, French château, Spanish castillo, Italian castello, the word castle was introduced into English shortly before the Norman Conquest to denote this type of building, which was then new to England. In its simplest terms, the definition of a castle accepted amongst academics is a fortified residence. Feudalism was the link between a lord and his vassal where, in return for service and the expectation of loyalty. Castles served a range of purposes, the most important of which were military, administrative, as well as defensive structures, castles were also offensive tools which could be used as a base of operations in enemy territory

Romanesque architecture
–
Romanesque Architecture is an architectural style of medieval Europe characterized by semi-circular arches. There is no consensus for the date of the Romanesque style, with proposals ranging from the 6th to the late 10th century. It developed in the 12th century into the Gothic style, marked by pointed arches, examples of Romanesque architecture can be found across the continent, making it the first pan-European architectural style since Imperial Roman Architecture. The Romanesque style in England is traditionally referred to as Norman architecture, each building has clearly defined forms, frequently of very regular, symmetrical plan, the overall appearance is one of simplicity when compared with the Gothic buildings that were to follow. The style can be identified right across Europe, despite regional characteristics, Many castles were built during this period, but they are greatly outnumbered by churches. The most significant are the great churches, many of which are still standing, more or less complete. The largest groups of Romanesque survivors are in areas that were less prosperous in subsequent periods, including parts of southern France, northern Spain and rural Italy. According to the Oxford English Dictionary, the word Romanesque means descended from Roman and was first used in English to designate what are now called Romance languages, Romance language is not degenerated Latin language. Latin language is degenerated Romance language, Romanesque architecture is not debased Roman architecture. Roman architecture is debased Romanesque architecture, the first use in a published work is in William Gunns An Inquiry into the Origin and Influence of Gothic Architecture. The term is now used for the more restricted period from the late 10th to 12th centuries, Many castles exist, the foundations of which date from the Romanesque period. Most have been altered, and many are in ruins. By far the greatest number of surviving Romanesque buildings are churches, the scope of Romanesque architecture Romanesque architecture was the first distinctive style to spread across Europe since the Roman Empire. In the more northern countries Roman building styles and techniques had never been adopted except for official buildings, although the round arch continued in use, the engineering skills required to vault large spaces and build large domes were lost. There was a loss of continuity, particularly apparent in the decline of the formal vocabulary of the Classical Orders. In Rome several great Constantinian basilicas continued in use as an inspiration to later builders, the largest building is the church, the plan of which is distinctly Germanic, having an apse at both ends, an arrangement not generally seen elsewhere. Another feature of the church is its regular proportion, the plan of the crossing tower providing a module for the rest of the plan. These features can both be seen at the Proto-Romanesque St. Michaels Church, Hildesheim, 1001–1030, the style, sometimes called First Romanesque or Lombard Romanesque, is characterised by thick walls, lack of sculpture and the presence of rhythmic ornamental arches known as a Lombard band

Gothic architecture
–
Gothic architecture is a style of architecture that flourished in Europe during the high and late medieval period. It evolved from Romanesque architecture and was succeeded by Renaissance architecture and its characteristics include the pointed arch, the ribbed vault and the flying buttress. Gothic architecture is most familiar as the architecture of many of the cathedrals, abbeys. It is also the architecture of many castles, palaces, town halls, guild halls, universities and to a less prominent extent, private dwellings, for this reason a study of Gothic architecture is largely a study of cathedrals and churches. A series of Gothic revivals began in mid-18th-century England, spread through 19th-century Europe and continued, largely for ecclesiastical and university structures, the term Gothic architecture originated as a pejorative description. Hence, François Rabelais, also of the 16th century, imagines an inscription over the door of his utopian Abbey of Thélème, Here enter no hypocrites, slipping in a slighting reference to Gotz and Ostrogotz. Authorities such as Christopher Wren lent their aid in deprecating the old medieval style, the Company disapproved of several of these new manners, which are defective and which belong for the most part to the Gothic. Gothic architecture is the architecture of the medieval period, characterised by use of the pointed arch. As an architectural style, Gothic developed primarily in ecclesiastical architecture, the greatest number of surviving Gothic buildings are churches. The Gothic style is most particularly associated with the cathedrals of Northern France. At the end of the 12th century, Europe was divided into a multitude of city states, norway came under the influence of England, while the other Scandinavian countries and Poland were influenced by trading contacts with the Hanseatic League. Angevin kings brought the Gothic tradition from France to Southern Italy, throughout Europe at this time there was a rapid growth in trade and an associated growth in towns. Germany and the Lowlands had large flourishing towns that grew in comparative peace, in trade and competition with other, or united for mutual weal. Civic building was of importance to these towns as a sign of wealth. England and France remained largely feudal and produced grand domestic architecture for their kings, dukes and bishops, the Catholic Church prevailed across Europe at this time, influencing not only faith but also wealth and power. Bishops were appointed by the lords and they often ruled as virtual princes over large estates. The early Medieval periods had seen a growth in monasticism, with several different orders being prevalent. Foremost were the Benedictines whose great abbey churches vastly outnumbered any others in France, a part of their influence was that towns developed around them and they became centers of culture, learning and commerce

Tower
–
A tower is a tall structure, taller than it is wide, often by a significant margin. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, Towers are specifically distinguished from buildings in that they are not built to be habitable but to serve other functions. Towers can be stand alone structures or be supported by adjacent buildings or can be a feature on top of a structure or building. Old English torr is from Latin turris via Old French tor, the Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, connected with the Illyrian toponym Βου-δοργίς. The oldest known may be the stone tower in walls of Neolithic Jericho. Some of the earliest towers were ziggurats, which existed in Sumerian architecture since the 4th millennium BC, the most famous ziggurats include the Sumerian Ziggurat of Ur, built the 3rd millennium BC, and the Etemenanki, one of the most famous examples of Babylonian architecture. The latter was built in Babylon during the 2nd millennium BC and was considered the tallest tower of the ancient world, some of the earliest surviving examples are the broch structures in northern Scotland, which are conical towerhouses. These and other examples from Phoenician and Roman cultures emphasised the use of a tower in fortification, for example, the name of the Moroccan city of Mogador, founded in the first millennium BC, is derived from the Phoenician word for watchtower. The Romans utilised octagonal towers as elements of Diocletians Palace in Croatia, which monument dates to approximately 300 AD, while the Servian Walls, the Chinese used towers as integrated elements of the Great Wall of China in 210 BC during the Qin Dynasty. Towers were also an important element of castles, other well known towers include the Leaning Tower of Pisa in Pisa, Italy built from 1173 until 1372 and the Two Towers in Bologna, Italy built from 1109 until 1119. The Himalayan Towers are stone towers located chiefly in Tibet built approximately 14th to 15th century, up to a certain height, a tower can be made with the supporting structure with parallel sides. However, above a height, the compressive load of the material is exceeded. This can be avoided if the support structure tapers up the building. A second limit is that of buckling—the structure requires sufficient stiffness to avoid breaking under the loads it faces, many very tall towers have their support structures at the periphery of the building, which greatly increases the overall stiffness. A third limit is dynamic, a tower is subject to varying winds, vortex shedding and these are often dealt with through a combination of simple strength and stiffness, as well as in some cases tuned mass dampers to damp out movements. Varying or tapering the outer aspect of the tower with height avoids vibrations due to vortex shedding occurring along the building simultaneously. Although not correctly called towers many modern skyscraper are often called towers, in the United Kingdom, tall domestic buildings are referred to as tower blocks. In the United States, the original World Trade Center had the nickname the Twin Towers, the tower throughout history has provided its users with an advantage in surveying defensive positions and obtaining a better view of the surrounding areas, including battlefields

Water well
–
A water well is an excavation or structure created in the ground by digging, driving, boring, or drilling to access groundwater in underground aquifers. The well water is drawn by a pump, or using containers, such as buckets, placing a lining in the well shaft helps create stability and linings of wood or wickerwork date back at least as far as the Iron Age. Wells have been sunk by hand digging as is the case in rural developing areas. These wells are inexpensive and low-tech as they use mostly manual labour, a more modern method called caissoning uses pre-cast reinforced concrete well rings that are lowered into the hole. Deeper wells can be excavated by hand drilling methods or machine drilling, using a bit in a borehole, drilled wells are usually cased with a factory-made pipe composed of steel or plastic. Drilled wells can access water at greater depths than dug wells. A collector well can be constructed adjacent to a lake or stream with water percolating through the intervening material. The site of a well can be selected by a hydrogeologist, Water may be pumped or hand drawn. Impurities from the surface can easily reach shallow sources and contamination of the supply by pathogens or chemical contaminants needs to be avoided, Well water typically contains more minerals in solution than surface water and may require treatment before being potable. Soil salination can occur as the water falls and the surrounding soil begins to dry out. Another environmental problem is the potential for methane to seep into the water, hand-dug wells are excavations with diameters large enough to accommodate one or more people with shovels digging down to below the water table. The excavation is braced horizontally to avoid landslide or erosion endangering the people digging, a more modern method called caissoning uses reinforced concrete or plain concrete pre-cast well rings that are lowered into the hole. A well-digging team digs under a ring and the well column slowly sinks into the aquifer. Hand-dug wells are inexpensive and low tech as they use mostly manual labour to access groundwater in rural locations in developing countries and they may be built with a high degree of community participation, or by local entrepreneurs who specialize in hand-dug wells. They have been excavated to 60 metres. They have low operational and maintenance costs, in part because water can be extracted by hand bailing, without a pump. The water is coming from an aquifer or groundwater, and can be easily deepened. The yield of existing hand dug wells may be improved by deepening or introducing vertical tunnels or perforated pipes, drawbacks to hand-dug wells are numerous

Defensive wall
–
A defensive wall is a fortification used to protect a city, town or other settlement from potential aggressors. In ancient to modern times, they were used to enclose settlements, beyond their defensive utility, many walls also had important symbolic functions – representing the status and independence of the communities they embraced. Existing ancient walls are almost always masonry structures, although brick, depending on the topography of the area surrounding the city or the settlement the wall is intended to protect, elements of the terrain may be incorporated in order to make the wall more effective. Walls may only be crossed by entering the city gate and are often supplemented with towers. Simpler defensive walls of earth or stone, thrown up around hillforts, ringworks, early castles, from very early history to modern times, walls have been a near necessity for every city. Uruk in ancient Sumer is one of the worlds oldest known walled cities, before that, the city of Jericho in what is now the West Bank had a wall surrounding it as early as the 8th millennium BC. The Assyrians deployed large labour forces to build new palaces, temples, some settlements in the Indus Valley Civilization were also fortified. By about 3500 B. C. hundreds of small farming villages dotted the Indus floodplain, many of these settlements had fortifications and planned streets. Mundigak in present-day south-east Afghanistan has defensive walls and square bastions of sun dried bricks, babylon was one of the most famous cities of the ancient world, especially as a result of the building program of Nebuchadnezzar, who expanded the walls and built the Ishtar Gate. Exceptions were few — notably, ancient Sparta and ancient Rome did not have walls for a long time, initially, these fortifications were simple constructions of wood and earth, which were later replaced by mixed constructions of stones piled on top of each other without mortar. In Central Europe, the Celts built large fortified settlements which the Romans called oppida, the fortifications were continuously expanded and improved. In ancient Greece, large stone walls had been built in Mycenaean Greece, in classical era Greece, the city of Athens built a long set of parallel stone walls called the Long Walls that reached their guarded seaport at Piraeus. Large tempered earth walls were built in ancient China since the Shang Dynasty, although stone walls were built in China during the Warring States, mass conversion to stone architecture did not begin in earnest until the Tang Dynasty. The large walls of Pingyao serve as one example, likewise, the famous walls of the Forbidden City in Beijing were established in the early 15th century by the Yongle Emperor. The Romans fortified their cities with massive, mortar-bound stone walls, the most famous of these are the largely extant Aurelian Walls of Rome and the Theodosian Walls of Constantinople, together with partial remains elsewhere. These are mostly city gates, like the Porta Nigra in Trier or Newport Arch in Lincoln, apart from these, the early Middle Ages also saw the creation of some towns built around castles. These cities were only protected by simple stone walls and more usually by a combination of both walls and ditches. From the 12th century AD hundreds of settlements of all sizes were founded all across Europe and these cities are easy to recognise due to their regular layout and large market spaces

Palisade
–
A palisade—sometimes called a stakewall or a paling—is typically a fence or wall made from wooden stakes or tree trunks and used as a defensive structure or enclosure. Typical construction consisted of small or mid-sized tree trunks aligned vertically, the trunks were sharpened or pointed at the top, and were driven into the ground and sometimes reinforced with additional construction. The height of a palisade ranged from around a metre to as high as 3-4 m, as a defensive structure, palisades were often used in conjunction with earthworks. Palisades were an excellent option for small forts or other hastily constructed fortifications, since they were made of wood, they could often be quickly and easily built from readily available materials. They proved to be effective protection for short-term conflicts and were a deterrent against small forces. However, because they were wooden constructions they were vulnerable to fire. Often, a palisade would be constructed around a castle as a wall until a permanent stone wall could be erected. They were frequently used in New France, both the Greeks and Romans created palisades to protect their military camps. The Roman historian Livy describes the Greek method as being inferior to that of the Romans during the Second Macedonian War, the Greek stakes were too large to be easily carried and were spaced too far apart. This made it easy for enemies to them and create a large enough gap in which to enter. In contrast, the Romans used smaller and easier to carry stakes which were placed closer together, many settlements of the native Mississippian culture of the Midwestern United States also made use of palisades. The most prominent example is the Cahokia Mounds site in Collinsville, a wooden stockade with a series of watchtowers or bastions at regular intervals formed a 2-mile-long enclosure around Monks Mound and the Grand Plaza. Archaeologists found evidence of the stockade during excavation of the area and indications that it was several times. The stockade seems to have separated Cahokias main ceremonial precinct from other parts of the city, the English settlements in Jamestown, Virginia and Plymouth, Massachusetts were originally fortified towns surrounded by palisades. In the late century, when milled lumber was not available or practical. The walls were made of vertical half timbers, the outside, rounded half with its still on faced Adirondack weather. Typically, the cracks between the logs were filled with moss and sometimes covered with small sticks. Inside, the cracks were covered with narrow wooden battens and it also presented a more finished look inside

Piast dynasty
–
The Piast dynasty was the first historical ruling dynasty of Poland. The first documented Polish monarch was Prince Mieszko I, the Piasts royal rule in Poland ended in 1370 with the death of king Casimir III the Great. Branches of the Piast dynasty continued to rule in the Duchy of Masovia, the Piasts intermarried with several noble lines of Europe, and possessed numerous titles, some within the Holy Roman Empire. However, the term Piast Dynasty was not applied until the 17th century, in a historical work the expression Piast dynasty was introduced by the Polish historian Adam Naruszewicz, it is not documented in contemporary sources. The first Piasts, probably of Polan descent, appeared around 940 in the territory of Greater Poland at the stronghold of Giecz, shortly afterwards they relocated their residence to Gniezno, where Prince Mieszko I ruled over the Civitas Schinesghe from about 960. The name Polani, from Slavic, pole, did not appear until 1015, the Piasts temporarily also ruled over Pomerania, Bohemia and the Lusatias, as well as Ruthenia, and the Hungarian Spiš region in present-day Slovakia. The ruler bore the title of a duke or a king, depending on their position of power. The Bohemian Přemyslid dynasty, the Hungarian Arpads and their Anjou successors, the Kievan Rus, later also the State of the Teutonic Order, the Piast position was decisively enfeebled by an era of fragmentation following the 1138 Testament of Bolesław III Krzywousty. Numerous dukes like Mieszko III the Old, Władysław III Spindleshanks or Leszek I the White were crowned, only to be overthrown shortly afterwards. After the Polish royal line and Piast junior branch had died out in 1370, the Masovian branch of the Piasts became extinct with the death of Duke Janusz III in 1526. The last ruling duke of the Silesian Piasts was George William of Legnica who died in 1675 and his uncle Count August of Legnica, the last male Piast, died in 1679. The last legitimate heir, Duchess Karolina of Legnica-Brieg died in 1707 and is buried in Trzebnica Abbey, nevertheless, numerous families, like the illegitimate descendants of the Silesian duke Adam Wenceslaus of Cieszyn, link their genealogy to the dynasty. About 1295, Przemysł II used a coat of arms with a white eagle – a symbol later referred to as the Piast coat of arms or as the Piast Eagle, Piast kings and rulers of Poland appear in list form in the following table. For a list of all rulers, see List of Polish monarchs
