Sliabh na Caillighe

Sliabh na Caillighe (the "Hill of the Witch" in English) or Loughcrew is a neolithic (3rd millenium BC) passage grave cemetery located on a series of hills near the village of Oldcastle in County Meath. The enigmatically(!) named "Cairn T" here is one of the best preserved of these tombs and is open to the public during the summer months.
