The Tower of London, officially His Majesty's Royal Palace and Fortress of the Tower of London, is a historic castle on the north bank of the River Thames in central London, England. It lies within the London Borough of Tower Hamlets, which is separated from the eastern edge of the square mile of the City of London by the open space known as Tower Hill. It was founded toward the end of 1066 as part of the Norman Conquest. The White Tower, which gives the entire castle its name, was built by William the Conqueror in 1078 and was a resented symbol of oppression, inflicted upon London by the new Norman ruling class. The castle was also used as a prison from 1100 until 1952, although that was not its primary purpose. A grand palace early in its history, it served as a royal residence. As a whole, the Tower is a complex of several buildings set within two concentric rings of defensive walls and a moat. There were several phases of expansion, mainly under kings Richard I, Henry III, and Edward I in the 12th and 13th centuries. The general layout established by the late 13th century remains despite later activity on the site.
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars usually consider a castle to be the private fortified residence of a lord or noble. This is distinct from a mansion, palace and villa, whose main purpose was exclusively for pleasance and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain walls, arrowslits, and portcullises, were commonplace.
Tattershall Castle is a castle in Tattershall, Lincolnshire, England, Since 1925 it has been in the care of the National Trust.
Chester Castle is in the city of Chester, Cheshire, England. It is sited at the southwest extremity of the area bounded by the city walls. The castle stands on an eminence overlooking the River Dee. In the castle complex are the remaining parts of the medieval castle together with the neoclassical buildings designed by Thomas Harrison which were built between 1788 and 1813. Parts of the neoclassical buildings are used today by the Crown Court and as a military museum. The museum and the medieval remains are a tourist attraction.
Criccieth Castle is a ruined thirteenth-century castle in Criccieth, Gwynedd, Wales. It is located on a rocky headland overlooking Tremadog Bay and consists of an inner ward almost surrounded by an outer ward. The twin-towered inner gatehouse is the most prominent remaining feature and survives to almost its full height, as does the inner curtain wall. The outer curtain wall, the inner ward buildings, and the castle's other three towers are significantly more ruinous, and in places survive only as foundations.
Château Gaillard is a medieval castle ruin overlooking the River Seine above the commune of Les Andelys, in the French department of Eure, in Normandy. It is located some 95 kilometres (59 mi) north-west of Paris and 40 kilometres (25 mi) from Rouen. Construction began in 1196 under the auspices of Richard the Lionheart, who was simultaneously King of England and feudal Duke of Normandy. The castle was expensive to build, but the majority of the work was done in an unusually short period of time. It took just two years and, at the same time, the town of Petit Andely was constructed. Château Gaillard has a complex and advanced design, and uses early principles of concentric fortification; it was also one of the earliest European castles to use machicolations. The castle consists of three enclosures separated by dry moats, with a keep in the inner enclosure.
Ewloe Castle is a native Welsh castle built by the Kingdom of Gwynedd near the town of Ewloe in Flintshire, Wales. The castle, which was one of the last fortifications to be built by the native Princes of Wales, was abandoned at the beginning of the invasion of Wales by Edward I in 1277. Its construction, using locally quarried sandstone, appears to have continued piecemeal over many years and may have not been completed. On taking the castle, the English Crown gave it little military value and allowed it to fall into ruin.
Pickering Castle is a motte-and-bailey fortification in Pickering, North Yorkshire, England.
Enceinte is a French term that refers to the "main defensive enclosure of a fortification". For a castle, this is the main defensive line of wall towers and curtain walls enclosing the position. For a settlement, it would refer to the main town wall with its associated gatehouses, towers, and walls.
Pevensey Castle is a medieval castle and former Roman Saxon Shore fort at Pevensey in the English county of East Sussex. The site is a scheduled monument in the care of English Heritage and is open to visitors. Built around 290 AD and known to the Romans as Anderitum, the fort appears to have been the base for a fleet called the Classis Anderidaensis. The reasons for its construction are unclear; long thought to have been part of a Roman defensive system to guard the British and Gallic coasts against Saxon pirates, it has more recently been suggested that Anderitum and the other Saxon Shore forts were built by a usurper in an ultimately unsuccessful attempt to prevent Rome from reimposing its control over Britain.
Scarborough Castle is a former medieval royal fortress situated on a rocky promontory overlooking the North Sea and Scarborough, North Yorkshire, England. The site of the castle, encompassing the Iron Age settlement, Roman signal station, an Anglo-Scandinavian settlement and chapel, the 12th-century enclosure castle and 18th-century battery, is a scheduled monument of national importance.
Celje Castle is a castle ruin in Celje, Slovenia, formerly the seat of the Counts of Celje. It stands on three hills to the southeast of Celje, where the river Savinja meanders into the Laško valley. Today, the castle is in the process of being restored. It was once the largest fortification on Slovenian territory.
Rötteln Castle, located above the Lörrach suburb of Haagen, lies in the extreme southwest corner of the German state of Baden-Württemberg, just 10 kilometres north-east of the Swiss City of Basel. The fortification was one of the most powerful in the southwest, and today, it is the third largest castle ruin in Baden.
A curtain wall is a defensive wall between fortified towers or bastions of a castle, fortress, or town.
A bailey or ward in a fortification is a leveled courtyard, typically enclosed by a curtain wall. In particular, an early type of European castle was known as a motte-and-bailey. Castles and fortifications may have more than one bailey, and the enclosure wall building material may have been at first in wood, and later transitioned to stone. Their layout depends both on the local topography and the level of fortification technology employed, ranging from simple enclosures to elaborate concentric defences. In addition to the gradual evolution of more complex fortification plans, there are also significant differences in regional traditions of military architecture regarding subdivisions into baileys.
Bergfried is a tall tower that is typically found in castles of the Middle Ages in German-speaking countries and in countries under German influence. Friar describes it as a "free-standing, fighting-tower". Its defensive function is to some extent similar to that of a keep in English or French castles. However the characteristic difference between a bergfried and a keep is that a bergfried was typically not designed for permanent habitation.
Münzenberg Castle is a ruined hill castle in the town of the same name in the Wetteraukreis, Hesse, Germany. It dates from the 12th century. It is one of the best preserved castles from the High Middle Ages in Germany.
An outer bailey or outer ward is the defended outer enclosure of a castle. It protects the inner bailey and usually contains those ancillary buildings used for the management of the castle or the supply of its occupants. These domestic buildings could include workshops, livestock stalls and stables; storage facilities such as barns, sheds and granaries, as well as quarters for servants such as maids, farm workers, and even the castle governors or castellans. In many cases there was also a brewery, a bakehouse and a kitchen, if the latter was not located in the hall or palas. An outer bailey was often called a base court in England. Depending on topography it could also be referred to as a lower bailey or lower ward, the keep being in the upper bailey or ward. Chepstow Castle has lower, middle and upper baileys.
A Zwinger is an open kill zone area between two defensive walls that is used for defensive purposes. Zwingers were built in the post-classical and early modern periods to improve the defence of castles and town walls. The term is usually left untranslated, but is sometimes rendered as "outer courtyard", presumably referring to the subsequent role of a Zwinger as a castle's defences became redundant and it was converted into a palace or schloss; however, this belies its original purpose as a form of killing ground for the defence. The word is linked with zwingen, "to force", perhaps because the Zwinger forced an enemy to negotiate it before assaulting the main defensive line. Essenwein states that the "main purpose of this feature was so that the besieging force could not reach the actual castle wall very easily with battering rams or belfries, but had to stop at the lower, outer wall; also that two ranks of archers, behind and above one another, could fire upon the approaching enemy".
Neideck Castle is a former high mediaeval nobleman's castle above the village of Streitberg, in the municipality of Wiesenttal in the Upper Franconian county of Forchheim in the German state of Bavaria. As a result of its exposed location above the valley of the Wiesent, it has become a symbol of Franconian Switzerland.
