Description

A ringwork on a low ridge above the village of Llanfor. It measures about 45m N-S and 37m E-W. It is surrounded by a bank 5.0 - 6.0 m high on the west, and 3.5 - 4.0m high on the east. The bank on the south side is only 0.5m high, and there is a levelled rectangular area at a lower level than the interior. This may indicate the presence of a gateway, or a later building, or quarrying. There is no ditch surviving on the north side, but a mound 1.2m high and some 14m long curves round the north side of the ringwork, so giving the impression of a ditch 4.0 - 5.0 m wide. A ditch may be found by excavation, and traces of a scarp on the east side may mark the outer edge of a counter scarp bank. The west side of the ringwork is badly eroded by quarrying and the effects of weathering around tree roots. The interior is some 14m wide by 26m long and is fairly level, with the exception of the disturbances on the south side. The height of the bank above the interior varies between 1.6m on the north and 0.5m on the west.

The monument is of national importance for its potential to enhance our knowledge of medieval settlement and defence. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques.
