Pen-y-Gaer, Meidrim, is a roughly triangular enclosure set upon a ridge, seeming to act as a promontory site. A bank and possible ditch cut off access from the west, where there is a possible subsiduary enclosure, whilst the remaing north and south sides seem to show scarps only. This monument has been described as a 'Concentric or Segmented Hill-slope Enclosure'.
