Description
Whitewell Ruins, which includes three structures designated A, B, and C, is an important archaeological site. The main building, Structure A, likely dates from the late 14th or 15th century and features a later vaulted extension. Although the original owner is unknown, it resembles an early manor house similar to Lydstep Palace. The functions of the other buildings are not clearly defined. Historical records from 1601 mention tenants John Thomas, David Meredith, and others, with subsequent references to Owen John Thomas in 1609 and John Thomas and Davie Meredith in 1618.
Structure B is a small building located to the east of the main structure, possibly consisting of fragments from several buildings, including a gable wall facing south that is separate from the main structure. The site is partially surrounded by low walls built from masonry similar to the ruins. These walls and any parts of the medieval Whitewell buildings outside the Ancient Monument boundary are included in the listing.
The site is listed as Grade I due to its archaeological significance as a late medieval group of buildings, with one structure of exceptional size likely comparable to the Palace at Lydstep.
