Description

Hardham Priory, the ruins of the Chapter House, is a scheduled ancient monument located in the garden of a farmhouse to the north-east of the house. This structure, which dates from the mid 13th century, is incorrectly labeled as a chapel on the Ordnance Survey Map and in various historical texts. The Chapter House is a rectangular building featuring three lancet windows in the east wall, along with one blocked lancet in both the north and south walls. The west wall includes an arcaded entrance, which has two painted openings, each divided into two sections, and a pointed archway between them. This archway is supported by thin clustered shafts and is adorned with dogtooth moulding on the soffit.
