HER: Clwyd Powys 458 (None)
NMR: SO 03 NE 1 (92028)

Prominent, roughly circular, univallate, contour hilfort located high above the River Honddu, a tributary of the River Usk, commanding the river at Honddu Isaf. Surrounding slopes moderate to strong on N to marshy valley, with land falling less on S and W and even less on E. Measures c. 70m by 75m with internal area 0.38ha. Defined by single, fairly strong, rampart with ditch with continuous counterscarp. Evidence of stone revetting on SW rampart. Ditch is infilled hollow on all sides except N where reduced to shelf. A 50m length of bank of sandstone rubble with flanking ditches extends to the NE and 14m width extends from the causewayed entrance for c. 50m. Unknown whether this is a contemporary feature or later. Levelled platform in interior attached to SE rampart is either a later fold or contemporary hut c. 10m across. Site suggested by Savory (1952, 15, 72) as medieval. Generally well preserved despite plough damage. Extensive system of small fields surround the fort. On 1st Ed. OS map (1888). Few investigations. Undated.
