They are the tallest standing stones in Wales, some 4 metres high. In 1723 Henry Rowlands described them as part of a ruinous circle of eight stones, some 16 metres across. 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. 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. 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.
The pit of a further stone, inside the circle, shows it was a 'blade-style' stone, with an alignment with the summer solstice sunrise and winter solstice sunset. From the Bryn Gwyn Stones the midsummer sun rises over the centre of Castell Bryn Gwyn.
In the 18th century a cottage was built with the wide stone as its end wall. Notches round its top show where roof timbers had been fitted. With the removal of the cottage (which had occupied an area inside the stone circle) the stones were used as a gateway through the field hedge.
