What is recorded here

Dunnarealt Island is a complete stone ringfort where a collapsed boulder wall still stands above a natural rock platform. Two rectangular stone chambers adjoin the main circuit, suggesting the fort contained domestic buildings as well as defences. The island sits south of Roshin Point and joins the mainland at low tide, exposing a place that may have been reached, defended and forgotten as the sea changed.

Internal diam. 19m. The 'Fort' takes up the complete area of the island and consists of a natural rock platform surrounded by a collapsed stone wall incorporating parts of the rock outcrop. Gaps between the wall and platform are packed with small stones and clay. The wall is very low from the interior and is made up of large boulders with a core of smaller stones. There are remains of a stone-built structure (DG065-012002-) in NE section of the site 7.5m externally and 5.55m internally N-S and 5.7m and 4.55m internally E-W. A second rectangular stone structure adjoins the NW corner of the first building. The remains of this are slighter and it is overgrown. Its dimensions would appear to be 5.6m externally and 3.25m internally N-S and 5.4m externally and 3.2m internally E-W. These structures may have originally adjoined the cashel wall. The island is situated S of Roshin Point and is attached to' the mainland at low tide. The above description was derived from the 'Archaeological Survey of County Donegal.
