The Bryn Gwyn Stones or Bryn Gwyn Standing Stones are neolithic stones in Brynsiencyn on Anglesey [1]. The Bryn Gwyn stones stand about 280 metres to the south-west of Castell Bryn Gwyn, on the low ridge some 2 m above the valley of the Afon Braint on the Isle of Anglesey in Wales [1]. They are the tallest standing stones in Wales, nearly 4 m high [1]. In 1723 Henry Rowlands described them as part of a ruinous circle of eight stones, some 16 m across [1]. An account of 1797 says that "ignorant country people supposing money was hid under them tore them up" and today only two stones, one slab and one pillar, stand in a modern field bank [1]. Nothing else is visible on the ground, but a 2008 excavation found three pits of standing stones, two containing stone stumps, consistent with the record by Rowlands [1]. Further excavations in 2010 identified the pits of three more removed standing stones, making seven identified in all of the eight expected to make up the original circle [1].
