Proleek Dolmen

Northeast of Dundalk, the R173 passes Cooley Peninsula and then arrives at Ballymascanlon, where stands the Proleek Dolmen (National Monument), with a 40.6 ton capstone borne on only three uprights. Tradition has it that anyone who can throw a pebble on to the capstone so that it remains on the top will have a wish fulfilllled.
