These granite rocks are the remains of a burial chamber known locally as the Temple of Deen. It is located near the village of Culdaff on the Inishowen Pennisula in co. Donegal. It dates from between 1500-2000 BC and is located in a beautiful spot with stunning views towards Trabrega Bay. On the original ordinance survey maps of Ireland, it was marked as a druid’s altar as this site was linked to pagan ceremonies. During the 19th century, the United Irish League held meetings here on Sunday afternoons to demand land reform. The meetings were attended by tenant farmers and prominent speakers who traveled from as far away as Dublin. During this time there was a revival and interest in all things Celtic and many ancient monuments were re-visited. It is interesting that they came here rather than to the monastic sites nearby. It is reputed that St Patrick visited this area in person and established the two early Christian monasteries that are located nearby called Cloncha and Carrowmore.
