Small lake 2.5 miles NNE of Bruff, Co. Limerick, widely known in Irish tradition for the wealth of neolithic remains to be found near its shores and under its waters. The light limestone soil of the area made it especially attractive to cultivators in earliest times. From Irish legend Gerald, EARL OF DESMOND, is said to have disappeared here in 1398 and to ride out in the moonlight every seventh year. A cave on Rockadoon Island in Lough Gur is one of several sites suggested as the entrance to Tír na nÓg [the Land of Youth].
