The name Poulnabrone literally means 'the hole of the sorrows' and it is one of the most famous Irish dolmens. The thin capstone sits on two high portal stones to create a chamber and a low cairn. This site dates back to about 2500 BC. Un-cremated remains were found in the chamber as well and a number of grave goods were found in the tomb: a polished stone axe, two stone disc beads, a perforated bone pendant, part of a bone pin, two quartz crystals, flint and chert arrowheads and scrapers and over 60 shards of coarse pottery. In the same area there are in the region of seventy other tombs.
