Sitting on a headland above the surfers' haven of Trecastle Bay, two miles south of Rhosneigr, Barclodiad y Gawres (the Giantess' Apronful) is Wales' largest neolithic tomb. When the original cross-shaped burial chamber of one of the most remarkable archaeological remains in the UK was excavated in the 1950s, archaeologists found five standing stones inside, decorated in spirals and zigzags similar to those found only inside the Bryn Celli Ddu mound and in Ireland's Boyne Valley.
Due to problems with vandalism, the entrance to the mound is now blocked by an iron gate, but the gate is unlocked during set hours. As you venture inside, feeling like Indiana Jones, you can explore the stone carvings for yourself.
