Enclosure castle
A fortified residence defended by walls and towers.
An enclosure castle is a type of fortified home or stronghold where walls and towers provide the main defense. These structures were typically made of wood or stone, though some later versions used brick. In castles without a central keep or great tower, the interior often housed buildings like the warden’s residence, barracks, kitchens, stables, and chapels. They were frequently built in conflict zones, especially border areas such as the England–Wales frontier. Some were new ringworks, while others were adapted from older wooden motte-and-bailey designs.
The first enclosure castles in England appeared soon after the Norman Conquest, serving as strongholds for the invaders. Their design evolved in the 12th century as crusaders brought back military ideas to their home fortresses. Most surviving examples date from the 13th century, though a few were built in the 14th. They are found across England, with many near the vulnerable Channel ports in Kent and Sussex, and along the Welsh borders under Edward I. Construction spanned from the reign of William I until at least the late 1300s, with Bodiam Castle as a late example. The definition is debated; some consider later residences like Thornbury Castle (built around 1511) as enclosure castles, even though they were designed more for living than for war.
Notable examples include Kenilworth Castle, Clitheroe Castle, and Ludlow Castle. In England, English Heritage protects numerous such sites. Ireland also has several, such as King John’s Castle in Carlingford.

Lore & Background
The first examples in England were constructed shortly after the Norman conquest, as strongholds for the occupiers. Their form developed in the 12th century as the military experience gained by the crusaders was introduced into their home residences. The majority of extant examples were built in the 13th century, though a few were built in the 14th century.
Reader's Guide
Enclosure castles represent a significant phase in medieval fortification, bridging the gap between early motte-and-bailey structures and later residential castles. They were constructed from the reign of William I until at least the late 14th century with the construction of Bodiam Castle. The definition of an enclosure castle is debatable, and many would consider later structures designed principally for residence instead of war, including Thornbury Castle built c. 1511, to be an enclosure castle. Many in England are under the protection of English Heritage, which has counted 126 examples. Their distribution across England, particularly near vulnerable channel ports in Kent and Sussex and along the Welsh borders under Edward I, highlights their strategic role in border defense and occupation.
