Uaigh na gCat, Cave of the Cats
Owenygat is a natural limestone cave, whose entrance was modified in the early medieval period by the construction of a souterrain, into which is incorporated an ogham stone. The cave is possibly the Cave of Crúachu, described as the Gateway to the Otherworld in the early Irish tale Echtra Nerai. Adjacent monuments are:
• a well-preserved ring barrow
• Relignaree, a ring fort 60m in diameter, enclosed within a bank 105m across, part of an extensive medieval field system
• another ring fort further south, with souterrain to its southwest
• Daithi's Stone - Coirthe Dearg, a red sandstone pillar, on a low mound surrounded by a low bank i.e a ring barrow. Charcoal beneath the bank provided a radiocarbon date of 200 BC.
• Cloghannacorp, an early Neolithic court tomb
