The Cloghmore Stone (from Irish: an Chloch Mhór meaning “the big stone”) is a 30 ton boulder lying 300m above the village on a flat area on the slopes of Slieve Martin. It is a glacial erratic which was likely carried from Scotland during the last ice age. Local folk tales suggest it was thrown by the giant Fionn mac Cumhaill from the Cooley Mountains on the other side of Carlingford Lough.
