Poulnabrone Dolmen

Poulnabrone dolmen (Poll na Brón in Irish) is an unusually large dolmen or portal tomb located in the Burren, County Clare, Ireland. Situated on one of the most desolate and highest points of the region, it comprises three standing portal stones supporting a heavy horizontal capstone, and dates to the Neolithic period, probably between 4200 BC and 2900 BC. It is the best known and most widely photographed of the approximately 172 dolmens in Ireland.
