Quadrangular castle

Bolton Castle, in England.

A quadrangular castle or courtyard castle is a type of castle characterised by ranges of buildings which are integral with the curtain walls, enclosing a central ward or quadrangle, and typically with angle towers. There is no keep and frequently no distinct gatehouse. The quadrangular form predominantly dates from the mid to late fourteenth century and signals the transition from defensively to domestically oriented great houses.

Quadrangular castles typically display a sophisticated and complex approach to the planning of internal social spaces.^[1][2] There are many Quadrangular castles around Britain, for example: Bodiam Castle in East Sussex, and Bolton Castle.
