A castle at Dingestow is recorded as being constructed 1184 and further noted in 1469. The earthwork remains include two enclosures, the upper being sub-rectangular, about 54m by 38m, the lower adjoins on the south-east and is about 36m by 60m. The castle is defined by ditches, or moats, except to the north-east where it is sited above a stream. There is a counterscarp to the north-west. Excavations in 1969 failed to locate any substantial masonry structures. (Coflein)

The monument consists of the remains of a castle mound, dating to the medieval period (c. 1066 -1540 AD). The site comprises two enclosures located on the SW side of the River Trothy. The upper, western, enclosure is roughly rectangular in plan and measures 54m NW/SE by 38m NE/SW. It is up to 7m high and defined by steep-sided banks that drop to the surrounding ditch on the W,S and E sides and to the river on the N side. It is probably of natural origin, enhanced by the digging of the ditch. The lower enclosure, possibly the Bailey, adjoins the upper enclosure on the SE side and measures 36m NE/SE by 60m NE/SW. The ditch measures between 3m and 5m wide and is up to 2.5m deep. There is a 5m wide causeway over the ditch on the SW side that probably represents an original entrance. Documentary evidence from Giraldus Cambrensis suggests that Dingestow was built in the early 1180s by Ranulf Poer, Sheriff of Herefordshire, before being destroyed in 1184. (Scheduling Report)

Gatehouse Comments

Some poor quality walls were found during the 1969 excavation. A possible motte may actually be a collapsed tower. The motte and bailey at Mill Wood, on the opposite bank of the River Trothy, is usual described as a precursor site to this castle and earlier historical references may actual refer to that site.
