Summary

Possible unfinished contour hillfort located on narrow NE-SW ridge of Glan-Frogan above The Brogan stream valley and Afon Cain to NW and Dyffryn Meifod and Afon Vyrnwy to SE and to NE of Bryngwyn Wood Hillfort (Atlas No 1421). Steep surrounding slopes. Previously described by OS 1972 and CPAT site visit 1978 as a modern feature associated with quarrying and that could still be the case. Possible bank and internal hollow along S part of NW side strengthened on slope to SW end of ridge (quarrying noted) and less certainly evidence of incipient bank running NE along edge of hilltop from quarry. No details of entrance. Dense woodland. Not scheduled. Site on 1st Ed. OS map (1884-86). Minimal investigations, undated.
