Graig Fawr Hillfort, Radnorshire

3D Model

Graig Fawr is a largely univallate hillfort with additional ditches and ramparts on the north side. The southern entrance and any associated defences have been removed by ploughing. The site is recorded as being actively ploughed in 1973.

The site has recently (August 2018) been identified as a possible vitrified fort. The upper rampart material at the north east and south west end has been subjected to intense heat over a narrow width at the crest resulting in the local mudstones and soil matrix melting and becoming fused. Just a few kilometres away, and within sight of this hillfort, Castle Bank hillfort has also been reported to show evidence of vitrification.

The fort interior and ground to the north was subsequently used for a post medieval rabbit warren and artificial warrens, often called pillow mounds because of their shape, are numerous.
