Turret

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 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.

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 ring-work 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 fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin fortis ("strong") and facere.

A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet, in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed "crenels", and a wall or building with them is called crenellated; alternative (older) terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation.

Scottish castles are buildings that combine fortifications and residence, built within the borders of modern Scotland. Castles arrived in Scotland with the introduction of feudalism in the twelfth century. Initially these were wooden motte-and-bailey constructions, but many were replaced by stone castles with a high curtain wall. During the Wars of Independence, Robert the Bruce pursued a policy of castle slighting. In the late Middle Ages new castles were built, some on a grander scale as "livery and maintenance" castles that could support a large garrison. Gunpowder weaponry led to the use of gun ports, platforms to mount guns and walls adapted to resist bombardment.

A gun turret is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation.

Japanese castles are fortresses constructed primarily of wood and stone. They evolved from the wooden stockades of earlier centuries, and came into their best-known form in the 16th century. Castles in Japan were built to guard important or strategic sites, such as ports, river crossings, or crossroads, and almost always incorporated the landscape into their defenses.

A bartizan, also called a guerite, garita, or échauguette, or spelled bartisan, is an overhanging, wall-mounted turret projecting from the walls of late medieval and early-modern fortifications from the early 14th century up to the 18th century. Most frequently found at corners, they protected a warder and enabled him to see his surroundings. Bartizans generally are furnished with oillets or arrow slits. The turret was usually supported by stepped masonry corbels and could be round, polygonal or square.

Scottish baronial or Scots baronial is an architectural style of 19th century Gothic Revival which revived the forms and ornaments of historical architecture of Scotland in the Late Middle Ages and the Early Modern Period. Reminiscent of Scottish castles, buildings in the Scots baronial style are characterised by elaborate rooflines embellished with conical roofs, tourelles, and battlements with Machicolations, often with an asymmetric plan. Popular during the fashion for Romanticism and the Picturesque, Scots baronial architecture was equivalent to the Jacobethan Revival of 19th-century England, and likewise revived the Late Gothic appearance of the fortified domestic architecture of the elites in the Late Middle Ages and the architecture of the Jacobean era.

Scrabo Tower is a 135 feet (41 m) high 19th-century lookout tower or folly that stands on Scrabo Hill near Newtownards in County Down, Northern Ireland. It provides wide views and is a landmark that can be seen from afar. It was built as a memorial to Charles Vane, 3rd Marquess of Londonderry and was originally known as the Londonderry Monument. Its architectural style is Scottish Baronial Revival.

Helen's Tower is a 19th-century folly and lookout tower near Bangor, County Down, Northern Ireland. It was built by the 5th Baron of Dufferin and Claneboye and named for his mother, Helen. He intended it as a shrine for poems, first of all a poem by his mother and then other poems that he solicited from famous poets over the years. Tennyson's Helen's Tower is the best known of them. The tower is a fine example of Scottish Baronial architecture. Helen's Tower inspired the design of the Ulster Tower, a war memorial at Thiepval, France.

The architecture of the United Kingdom, or British architecture, consists of a combination of architectural styles, dating as far back to Roman architecture, to the present day 21st century contemporary. England has seen the most influential developments, though Ireland, Scotland, and Wales have each fostered unique styles and played leading roles in the international history of architecture. Although there are prehistoric and classical structures in the United Kingdom, British architectural history effectively begins with the first Anglo-Saxon Christian churches, built soon after Augustine of Canterbury arrived in Great Britain in 597. Norman architecture was built on a vast scale throughout Great Britain and Ireland from the 11th century onwards in the form of castles and churches to help impose Norman authority upon their dominions. English Gothic architecture, which flourished between 1180 until around 1520, was initially imported from France, but quickly developed its own unique qualities.

The architecture of Scotland includes all human building within the modern borders of Scotland, from the Neolithic era to the present day. The earliest surviving houses go back around 9500 years, and the first villages 6000 years: Skara Brae on the Mainland of Orkney being the earliest preserved example in Europe. Crannogs, roundhouses, each built on an artificial island, date from the Bronze Age and stone buildings called Atlantic roundhouses and larger earthwork hill forts from the Iron Age. The arrival of the Romans from about 71 AD led to the creation of forts like that at Trimontium, and a continuous fortification between the Firth of Forth and the Firth of Clyde known as the Antonine Wall, built in the second century AD. Beyond Roman influence, there is evidence of wheelhouses and underground souterrains. After the departure of the Romans there were a series of nucleated hill forts, often utilising major geographical features, as at Dunadd and Dunbarton.

The architecture of Scotland in the Middle Ages includes all building within the modern borders of Scotland, between the departure of the Romans from Northern Britain in the early fifth century and the adoption of the Renaissance in the early sixteenth century, and includes vernacular, ecclesiastical, royal, aristocratic and military constructions. The first surviving houses in Scotland go back 9500 years. There is evidence of different forms of stone and wooden houses exist and earthwork hill forts from the Iron Age. The arrival of the Romans led to the abandonment of many of these forts. After the departure of the Romans in the fifth century, there is evidence of the building of a series of smaller "nucleated" constructions sometimes utilizing major geographical features, as at Dunadd and Dumbarton. In the following centuries new forms of construction emerged throughout Scotland that would come to define the landscape.

Architecture in early modern Scotland encompasses all building within the borders of the kingdom of Scotland, from the early sixteenth century to the mid-eighteenth century. The time period roughly corresponds to the early modern era in Europe, beginning with the Renaissance and Reformation and ending with the start of the Enlightenment and Industrialisation.

The Towers is a small English country house situated in Sheffield, England. The house stands on Sandygate Road close to the junction with Coldwell Lane in the suburb of Crosspool. It is a Grade II listed building as is the lodge and attached gateway and the concave garden wall. It has been described as “an extraordinary Scottish baronial fantasy”.

In fortification architecture, a rampart is a length of bank or wall forming part of the defensive boundary of a castle, hillfort, settlement or other fortified site. It is usually broad-topped and made of excavated earth and/or masonry.

A cap-house is a small watch room, built at the top of a spiral staircase, often giving access to a parapet on the roof of a tower house or castle. They provided protection from the elements by enclosing the top of the stairway, and sometimes incorporated windows or gun loops. They were built in various forms, including square turrets, simple boxes, or small houses with gabled rooves, which were sometimes large enough to provide accommodation for a look-out.
