Caister Hall

Caister Hall is a house that originally served as 15th-century outbuildings to Caister Castle and may include remains of the outer courtyard. It was rebuilt in the 1830s and is constructed of brick and colourwashed brick, topped with slate roofs. The building has an L-shaped plan, featuring a 15th-century drum tower at the south-west corner, which is three stories high. The entrance doorway and ground floor windows are from the 20th century, while rectangular windows above are placed at irregular intervals on each floor. The building has a parapet and a flat roof added in the 20th century.

To the north, there is a 15th-century wing that has been significantly altered, standing two stories tall. This wing has a doorway and one renewed cross casement window on each floor, with the lower window having three lights and the upper having two. It features a gabled roof with a partly external stack at the north gable end. Adjacent to this is a two-story 15th-century brick structure that stands over a segmental arch, which historically allowed barges to deliver bricks and materials for the castle's construction. There is one rectangular window on each floor above the arch, with the ground floor window having an ashlar surround. The gabled roof of this structure is complemented by an arch that survives on the east side.

The main east wing, built in the 19th century, is two stories high with a four-bay north elevation. It features a bowed porch to the left of the center, which has a panelled door flanked by one 20th-century window on each side. Above the door is a four-vaned fanlight, and the brick doorcase carries an open pediment. The windows throughout this wing are sashes with glazing bars, set beneath gauged skewback arches, except for the west bay of the ground floor, which has a cross casement window. The gabled roof has four ridge stacks and a modest cupola above the door.
