 South east of the keep was the hall , built by Roger Clifford in the late 14th century as a replacement for an earlier hall . It provided space for the castle 's garrison , swelled by the Anglo @-@ Scottish Wars , and was a location for the lord to eat with his soldiers . The hall had large windows which may have detracted from the building 's defensive capability , although it has been postulated that casements bore large wooden shutters . The kitchen , which served the entire castle , was set in the south @-@ east corner of the fortification . Along the south wall were arranged more lodgings , a well , and a chapel , the latter another addition by Roger Clifford . In the south @-@ west corner of the castle was the Tower of League , built around 1300 by Roger Clifford . It included further rooms for accommodation , but notably would also have allowed defenders to fire on an enemy emerging from the gatehouse . Four storeys tall and with a single room at each level , the presence of a garderobe and fireplace on each floor suggests that the tower was reserved for high @-@ status visitors . The tower 's square plan is typical of such structures built in northern England at this time , as seen at castles such as Warkworth and Egremont , although it contrasts with rounded towers preferred in the south .
