Description

The retaining wall to the inner courtyard at Thurland Castle dates from the 1880s, while the adjoining tower base is likely from the 14th century. The wall is constructed of sandstone rubble and features a saddle-backed coping. At the northern end, there is a doorway with an elliptical arch and a flight of stone steps that lead down to a lower level. The wall terminates at its south-eastern end with an octagonal pier. On the south-western side, there is the base of a rectangular tower that has a weathered plinth. The eastern wall of the tower includes a chamfered doorway with a chamfered surround on its inner side. Inside the tower, the ceiling is barrel-vaulted.
