Fodor's Expert Review Poulnabrone Megalithic Tomb
The biggest and most famous of the Burren's megalithic tombs, Poulnabrone ("the hole of sorrows") is a portal grave/dolmen with a massive capstone and a majestic presence amid the craggy limestone fields shouldering the moody gray Burren skies. The monument was built around 4,500 years ago. Stand downwind and you might hear ancient whispers. There is a designated car park nearby with a historical timeline and a short gravel walkway to the dolmen (freely accessible). It's open and windy here, so grab an extra layer.
