1. The best preserved of these [medieval grange gardens] is Monknash, which lies close to the coast of Glamorgan (O.S. SS 9194 7057). Its enclosure of over 20 acres, comprises a basically concentric segmental arrangement of robbed walls, at least on the north and east where banks survive. It is watered by the Nash Brook, possibly includes a fishpond (E. Whittle pers comm.) and preserves both the upstanding walls of a 'grange' building and a substantial dove-cote base (RCAM 1984, 262-5, fig. 144; FIG. 1).

2. It is presumed that at least some of the earthwork remains of Monknash Grange (Nprn19355) represent structured garden layouts.
