slieve gullion

On the south summit is a cairn containing what is claimed to be the highest passage-tomb in Britain or Ireland. A 25-ft long lintelled passage, originally even longer, leads to an octagonal chamber constructed of upright stones which bore a now vanished corbelled roof. Excavations in 1961 showed cremation to have been the dominant burial rite practised in the tomb. Furthermore north, and at a level around 140 ft lower, is the north cairn, which contained two cists for the burial of cremated remains which may, however, have been deposited as secondary burials.
