Summary :
An univallate hillfort with a stone bank up to 3.1m high externally, 0.6m internally with a 10m wide ditch to the north. The eastern entrance is in-turned for 20m.

An excavation in 2010 by Clwyd-Powys Archaeological Trust identified the remains of two successive roundhouses and at least two phases of occupation. The earlier structure survived as a narrow drip gully around 7m in diameter which had been partly overlain by a levelled platform for a later roundhouse of similar dimensions.

The very southern edge of this Scheduled Ancient Monument lies within the Cae Llewelyn farm boundary.

An excavation in 2010 by Clwyd-Powys Archaeological Trust identified the remains of two successive roundhouses and at least two phases of occupation. The earlier structure survived as a narrow drip gully around 7m in diameter which had been partly overlain by a levelled platform for a later roundhouse of similar dimensions. The excavation results demonstrated good preservation of significant archaeological deposits within the interior of the hillfort. However, the minimal depth of the overburden across the site is testament to the fragile nature of the survival of the archaeological resource (Grant, 2010).

(MW Feb 2019) The base of the northern in-turned entrance bank has been eroded by footpath activity and displays some coursed stone. There in aircraft crash site within the scheduled monument boundary of the hillfort on the east side - see PRN 123698. A 10cm resolution digital surface model of the hillfort was created by drone photogrammetry in Feb 2019.
