Corsbie Castle

The castle formerly had five storeys, and a vaulted basement.^[1] It is constructed on a raised piece of ground, and is surrounded by a bog on all sides, the only access being by way of a causeway from the north. The castle was oblong, about 40 feet (12 m) by 27 feet (8.2 m); the average thickness of the walls is 6 feet (1.8 m). Only the walls to the south and east remain; they rise to 50 feet (15 m). Its rounded angles are constructed of dressed ashlar, while the rest of the masonry is of coursed rubble. There are remains of the earthworks, comprising the inner and outer banks of a medial ditch; these are best preserved towards the south west of the structure.^[2]
