1) The earthwork remains of a sub-rectangular platform are visible on 0.25m lidar east of Ogof Hir, Bardsey Island. The platform comprises a sub-rectangular bank enclosing an area of approximately 5.5m x 10m. There appears to be a break in the eastern bank which could be possibly an original entrance, however, due to the shallow nature of the earthwork this is not certain.

Previously, the shape and nature of the feature has led to interpretations suggesting that this feature could have been one of a group of several possible medieval longhouses at this location on the island. However, excavations carried out by Gwynedd Archaeological Trust in 1982 prompted a change in interpretation. The excavation confirmed that the feature was entirely constructed of turf, unlikely to have previously supported a roof. The lack of finds also meant that dating was not possible on this occasion. It is possible that this feature would have always been open-topped, possibly having been some form of structure used for drying seaweed for example (Kenny & Hopewell, 2015).

A field visit was undertaken by L. Barker, T. Driver and D. Hunt 19-21/05/18 as part of the CHERISH Project. Ground investigation found the earthwork to be indiscernible.

The feature has been digitally mapped and updated from 0.25m Lidar as part of the CHERISH Project.
