Enclosure about 100m east south east of Llawr-y-cwm-mawr. It first appears on the first edition of the 25-inch Ordnance Survey map, published in 1905. A photograph taken by Arthur Chater in 1969 shows the enclosure consists of a low, dry-stone wall, with two trees growing either side of the entrance. The enclosure is roughly square, measuring approximately 15m east-west by 16m north-south. It is no longer recorded on modern editions of the Ordnance Survey maps.
