Poulnabrone dolmen (Poll na mBrón in Irish, meaning "hole of the quern stones" (bró in Irish)) is a portal tomb - one of approximately 174 in Ireland - located in the Burren, County Clare, Ireland. It dates back to the Neolithic period, probably between 4200 BC and 2900 BC. It is situated 8 km (5 miles) south of Ballyvaughan, 9.6 km (6 miles) north-west of Kilnaboy. It was raining pretty hard when I shot this. I was hoping to shoot it in better light but did not get the chance. Color Version: http://www.pbase.com/dlgphoto/image/165924628
