A small rectangular building (7m x 4) is shown on OS 1st edition 25in mapping with a small mill pond (11m x 5m) to the south. Tracks servicing the mill lead to Gribin-dauddwr in the south and Cilwenen in the east. Modern mapping appears to suggest that three walls of building may remain, but the area is under heavy tree cover and so this must remain uncertain. Modern aerial photographic coverage confirms that the three buildings at Gribin-dauddwr (SM99733812) are no longer extant.
