Thje surviving remains at Bonville's Castle consist of a masonry block that shows the remains of corbelled parapets. This apparently once adjoined a further range and hall, as described and illustrated in 1868 by Barnwell 1868. It is depicted on the Ordnance Survey County series map (Pembroke. XXXV.15 1889; 1907). The site was subsequently subsumed by colliery tipping (see NPRN 308432).
