In the 13th and 14th centuries, the castle was expanded by the Hastings family, including the addition of western towers which provided residential chambers. Two towers, one circular and one polygonal, were probably built between 1295 and 1314 by John Hastings, 1st Baron Hastings. This was the same time in which murage taxes were collected from local residents to fund the building of the town walls. Between the late 13th century and the early 14th century, a new wall was built.
