Medieval fortification refers to medieval military methods that cover the development of fortification construction and use in Europe, roughly from the fall of the Western Roman Empire to the Renaissance. During this millennium, fortifications changed warfare, and in turn were modified to suit new tactics, weapons and siege techniques.
A castle is a type of fortified structure built during the Middle Ages predominantly by the nobility or royalty and by military orders. Scholars debate the scope of the word castle, but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for royalty or nobility; from a pleasance which was a walled-in residence for nobility, but not adequately fortified; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Use of the term has varied over time and has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the approximately 900 years 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.
Pembroke Castle is a medieval castle in the centre of Pembroke, Pembrokeshire in Wales. The castle was the original family seat of the Earldom of Pembroke. A Grade I listed building since 1951, it underwent major restoration during the early 20th century.
Castles have played an important military, economic and social role in Great Britain and Ireland since their introduction following the Norman invasion of England in 1066. Although a small number of castles had been built in England in the 1050s, the Normans began to build motte and bailey and ringwork castles in large numbers to control their newly occupied territories in England and the Welsh Marches. During the 12th century the Normans began to build more castles in stone – with characteristic square keep – that played both military and political roles. Royal castles were used to control key towns and the economically important forests, while baronial castles were used by the Norman lords to control their widespread estates. David I invited Anglo-Norman lords into Scotland in the early 12th century to help him colonise and control areas of his kingdom such as Galloway; the new lords brought castle technologies with them and wooden castles began to be established over the south of the kingdom. Following the Norman invasion of Ireland in the 1170s, under Henry II, castles were established there too.
A portcullis is a heavy vertically-closing gate typically found in medieval fortifications, consisting of a latticed grille made of wood, metal, or a combination of the two, which slides down grooves inset within each jamb of the gateway.
Harlech Castle in Harlech, Gwynedd, Wales, is a Grade I listed medieval fortification built onto a rocky knoll close to the Irish Sea. It was built by Edward I during his invasion of Wales between 1282 and 1289 at the relatively modest cost of £8,190. Over the next few centuries, the castle played an important part in several wars, withstanding the siege of Madog ap Llywelyn between 1294 and 1295, but falling to Prince Owain Glyndŵr in 1404. It then became Glyndŵr's residence and military headquarters for the remainder of the uprising until being recaptured by English forces in 1409. During the 15th century Wars of the Roses, Harlech was held by the Lancastrians for seven years, before Yorkist troops forced its surrender in 1468, a siege memorialised in the song "Men of Harlech". Following the outbreak of the English Civil War in 1642, the castle was held by forces loyal to Charles I, holding out until 1647 when it became the last fortification to surrender to the Parliamentary armies. In the 21st century the ruined castle is managed by Cadw, the Welsh Government's historic environment service, as a tourist attraction.
Conwy Castle is a fortification in Conwy, located in North Wales. It was built by Edward I, during his conquest of Wales, between 1283 and 1287. Constructed as part of a wider project to create the walled town of Conwy, the combined defences cost around £15,000, a massive sum for the period. Over the next few centuries, the castle played an important part in several wars. It withstood the siege of Madog ap Llywelyn in the winter of 1294–95, acted as a temporary haven for Richard II in 1399 and was held for several months by forces loyal to Owain Glyndŵr in 1401.
Bodiam Castle is a 14th-century moated castle near Robertsbridge in East Sussex, England. It was built in 1385 by Sir Edward Dalyngrigge, a former knight of Edward III, with the permission of Richard II, ostensibly to defend the area against French invasion during the Hundred Years' War. Of quadrangular plan, Bodiam Castle has no keep, having its various chambers built around the outer defensive walls and inner courts. Its corners and entrance are marked by towers, and topped by crenellations. Its structure, details and situation in an artificial watery landscape indicate that display was an important aspect of the castle's design as well as defence. It was the home of the Dalyngrigge family and the centre of the manor of Bodiam.
A machicolation is a floor opening between the supporting corbels of a battlement, through which stones or other material, such as boiling water, hot sand, quicklime or boiling cooking oil, could be dropped on attackers at the base of a defensive wall. A smaller version found on smaller structures is called a box-machicolation.
A keep is a type of fortified tower built within castles during the Middle Ages by European nobility. Scholars have debated the scope of the word keep, but usually consider it to refer to large towers in castles that were fortified residences, used as a refuge of last resort should the rest of the castle fall to an adversary. The first keeps were made of timber and formed a key part of the motte-and-bailey castles that emerged in Normandy and Anjou during the 10th century; the design spread to England, south Italy and Sicily. As a result of the Norman invasion of 1066, use spread into Wales during the second half of the 11th century and into Ireland in the 1170s. The Anglo-Normans and French rulers began to build stone keeps during the 10th and 11th centuries; these included Norman keeps, with a square or rectangular design, and circular shell keeps. Stone keeps carried considerable political as well as military importance and could take up to a decade or more to build.
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.
Fort la Latte, or the Castle of the Rock Goyon, is a castle in the northeast of Brittany, about 4 kilometres (2.5 mi) southeast of Cap Fréhel and about 35 kilometres (22 mi) west of Saint-Malo, in the commune of Plévenon, Côtes-d'Armor.
The Castles and Town Walls of King Edward in Gwynedd is a UNESCO-designated World Heritage Site located in Gwynedd, Wales. It includes the castles of Beaumaris and Harlech and the castles and town walls of Caernarfon and Conwy. UNESCO considers the sites to be the "finest examples of late 13th century and early 14th century military architecture in Europe".
A shell keep is a style of medieval fortification, best described as a stone structure circling the top of a motte.
A curtain wall is a defensive wall between two fortified towers or bastions of a castle, fortress, or town.
Vushtrri Castle or Old Tower is a city fortifications in Vushtrri, Kosovo. It was the seat of despot Đurađ Branković (1427–1456). Later chroniclers are noted that the fort itself is derived from the times of Dušan, and that it is an old fortress with a tower in the middle of the town.
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.
Rochester Castle stands on the east bank of the River Medway in Rochester, Kent, South East England. The 12th-century keep or stone tower, which is the castle's most prominent feature, is one of the best preserved in England or France.
An elevated entrance is a type of entrance, common in the design of medieval castles, that is not accessible from ground level, but lies at the level of an upper storey. The elevated entrance is the lowest and frequently the only way of entering a fortified building or residence. In the case of circular towers, a large opening in the main wall at ground level was a potential weakness and experts on castle design have argued that the elevated entrance served a structural as well as defensive purpose.
The Louvre Castle, also known as the Medieval Louvre, was a castle built by King Philip II of France on the right bank of the Seine, to reinforce the city wall he had built around Paris. It was demolished in stages between 1528 and 1660 to make way for the expanded Louvre Palace.
