Wedge Tomb by Usna
The Wedge Tomb of Usna ( Irish Osna ), marked on historical maps as Dermot and Grania's Bed , is located on the grounds of the Carrick-on-Shannon Golf Club, east of Boyle (Irish Mainistir na Buille ) in County Roscommon in Ireland . The Wedge Tomb was excavated by Ruaidhrí de Valera and described as fairly well preserved by Seán Ó Nualláin. Wedge Tombs ( German "Keilgräber" ), formerly also called "wedge-shaped gallery grave", are aisle-free, mostly undivided megalithic complexes from the late Neolithic and early Bronze Age .
description
The approximately 8.5 m long west-east oriented chamber is 1.0 to 1.7 m wide and is surrounded in a U-shape by a partially preserved outer wall. The gallery is divided by an about 1.5 m long antechamber in the west, which is separated by a high stone that rises 0.4 m higher than the side stones. The eastern end of the gallery is covered by a 3.2 m long, 2.3 m wide and 0.45 m thick capstone. Seven bearing stones (all between 0.2 and 0.85 m high) have been preserved on the north side and ten on the south side. At the west end of the stand Ante stones of the antechamber 1.5 m apart.
The wedge tomb was located in a trapezoidal stone mound about 10 m long and 2.5 m wide on the east and 7.5 m on the west side, which was defined by curbs. Today it is preserved as a round, grassy hill with a diameter of 24 m and a height of 1.6 to 2.0 m, from which only the capstone of the gallery protrudes.
