Megalithic tomb in Parknasilloge

Situated on a gentle E/NE-facing slope, on the SW side of the Glencullen River valley. A small chamber formed by two parallel slabs supporting a split boulder capstone (L 1.7m; Wth 0.7m at W - 0.61m at E; max. H 0.77m). The chamber is open at the W side but a displaced slab at the E end may have been a backs tone. It stands in the centre of a roughly circular cairn (diam. 7m; max. H 0.5m) which is slightly flattened along the W side. The OS Letters (O'Flanagan 1928, 7) state that the chamber stood at the centre of a 'small circular enclosure, unbroken, and consisting of twelve large stones, some laid flat but deep in the ground, others set on edge' - possibly a kerb. There are several boulders piled around the chamber some of which may have formed part of this feature. The above description is derived from the published 'Archaeological Inventory of County Wicklow' (Dublin: Stationery Office, 1997). In certain instances the entries have been revised and updated in the light of recent research.
