On the grounds of Mount Venus are the remains of a cromlech, the table stone of which has fallen ; and of the upright stones on which it was supported, one only is standing, the others lying near it. The whole is of granite ; the table stone is 19 feet long, 10 feet broad, and 5 feet thick ; and the pillars are about 10 feet in height. The burial ground of the old church, now a ruin, is still much used.
