Image of Barclodiad-y-Gawres (Chambered Cairn) by Kammer

Taken 2nd August 2003: OK, so it probably looked nothing like this originally, but the outside of Barclodiad-y-Gawres is almost as distinctive as the inside (in a nasty concrete sort of way). This shot was taken from nearby Port Nobla Cairn.
