Castell Perthi-mawr
Primary Reference Number (PRN) : 4780 Trust : Dyfed Community : Ciliau Aeron Unitary authority : Ceredigion NGR : SN52835897 Site Type (preferred type first) : Iron Age Hillfort Status : Scheduled Monument
Summary : Castell Perthi-mawr is a bivallate hillfort occupying a commanding position at 270m above sea level. The hill slopes steeply away from the site in all directions, but particularly to the east. The ramparts are widely spaced and consist of banks up to 2m high, but with no obvious traces of a ditch. The inner rampart shows traces of dry-stone walling - it is probably likely that both are stone built. The entrance lies on the northwest side. The outer terminals at the entrance are slightly overlapping and possibly club-ended, and the simple gap through the inner bank is off-set from the outer, giving a slight zig-zag entrance arrangement. The oval internal area measures approximately 112m by 60m, and does not seem to have been cultivated. The footings of a round-house 6m in diameter can be made out below the turf, and hollows may mark the site of further houses. Under rough pasture. There is some erosion on the inner face of the inner bank on the west side. K Murphy 15 December 2005 - taken from various descriptions.
Description : Site identified on LiDAR in 2019, earthworks clearly visible and appear to still be intact. The earthwork is 'egg' shaped and is orientated roughly east to west. The internal enclosure is approximately 104m x 52m. JS 2020
