A tower castle is a small castle that mainly consists of a fortified tower or a tower-like structure that is built on natural ground. It is thus different from the motte-and-bailey castle, which it may resemble, but whose main defensive structure is built on a motte or artificial hill. The tower castle is occasionally also described as a tower house castle or a tower house.
Sometimes, during the development of a castle, it might be converted from a tower castle to a motte-and-bailey type, if the initial, ground level site is later remodelled by the construction of an artificial mound for the keep or Bergfried . The habitable but also fortified tower castle became the permanent private residence of numerous lords during the 11th and 12th centuries.
Since many tower castles had at least a few additional structures such as a curtain wall, often only a few metres long, its overlap with an "ordinary" castle is fluid, as is its transition to the fortified house.
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; and from a fortified settlement, which was a public defence – though there are many similarities among these types of construction. Usage of the term has varied over time and has been applied to structures as diverse as hill forts and country houses. Over the approximately 900 years that 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.
York Castle is a fortified complex in the city of York, England. It consists of a sequence of castles, prisons, law courts and other buildings, which were built over the last nine centuries on the south side of the River Foss. The now-ruined keep of the medieval Norman castle is commonly referred to as Clifford's Tower. Built originally on the orders of William I to dominate the former Viking city of Jórvík, the castle suffered a tumultuous early history before developing into a major fortification with extensive water defences. After a major explosion in 1684 rendered the remaining military defences uninhabitable, York Castle continued to be used as a jail and prison until 1929.
A motte-and-bailey castle is a fortification with a wooden or stone keep situated on a raised area of ground called a motte, accompanied by a walled courtyard, or bailey, surrounded by a protective ditch and palisade. Relatively easy to build with unskilled labour, but still militarily formidable, these castles were built across northern Europe from the 10th century onwards, spreading from Normandy and Anjou in France, into the Holy Roman Empire in the 11th century. The Normans introduced the design into England and Wales following their invasion in 1066. Motte-and-bailey castles were adopted in Scotland, Ireland, the Low Countries and Denmark in the 12th and 13th centuries. Windsor Castle, in England, is an example of a motte-and-bailey castle. By the end of the 13th century, the design was largely superseded by alternative forms of fortification, but the earthworks remain a prominent feature in many countries.
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.
The Castle, Newcastle, or Newcastle Castle is a medieval fortification in Newcastle upon Tyne, England, built on the site of the fortress that gave the City of Newcastle its name. The most prominent remaining structures on the site are the Castle Keep, the castle's main fortified stone tower, and the Black Gate, its fortified gatehouse.
A tower house is a particular type of stone structure, built for defensive purposes as well as habitation. Tower houses began to appear in the Middle Ages, especially in mountainous or limited access areas, in order to command and defend strategic points with reduced forces. At the same time, they were also used as an aristocrat's residence, around which a castle town was often constructed.

Christchurch Castle is located in Christchurch, Dorset, England. The earliest stonework has been dated to 1160. It is a Norman motte and bailey castle. The castle's site is inside the old Saxon burh dominating the River Avon's lowest crossing.
Duffus Castle, near Elgin, Moray, Scotland, was a motte-and-bailey castle and was in use from c.1140 to 1705. During its occupation it underwent many alterations. The most fundamental was the destruction of the original wooden structure and its replacement with one of stone. At the time of its establishment, it was one of the most secure fortifications in Scotland. At the death of the 2nd Lord Duffus in 1705, the castle had become totally unsuitable as a dwelling and so was abandoned.
The inner bailey or inner ward of a castle is the strongly fortified enclosure at the heart of a medieval castle. It is protected by the outer ward and, sometimes also a Zwinger, moats, a curtain wall and other outworks. Depending on topography it may also be called an upper bailey or upper ward.
While there are many castles in South Yorkshire, the majority are manor houses and motte-and-bailey which were commonly found in England after the Norman Conquest.
A ringwork is a form of fortified defensive structure, usually circular or oval in shape. Ringworks are essentially motte-and-bailey castles minus the motte. Defences were usually earthworks in the form of a ditch and bank surrounding the site.
Bleddfa Castle was a motte and bailey structure near Llangunllo in modern-day Powys, Wales. It is believed to have been built before 1195 and abandoned by 1304. What remains today is described as a "mutilated oval mound" of 46 by 36 metres, containing some traces of masonry. It is surrounded by a rectangular bailey measuring 100 by 60 metres, with a hedge on its northern border.
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.
