Bryn Gwyn stones

Bryn Gwyn is a Neolithic stone circle on Anglesey consisting of eight stones originally positioned in a ring formation. Two tall stones remain visible today, standing on a low ridge adjacent to the Afon Braint river valley.

First recorded in 1723 by antiquarian Henry Rowlands, the circle was disrupted in 1797 when locals dug beneath the stones seeking buried treasure. Archaeological work from 2008 to 2010 later revealed the ritual deposits left by prehistoric people.

The stones mark a place where people gathered and honored their dead in prehistoric times, leaving traces of their rituals in the soil. Visitors today encounter the same landscape where ancestors found meaning and connection to the turning seasons.

Access is via a footpath departing from the A4080 road near Bryngwyn-mawr, which leads across open moorland to the ridge where the stones stand. The terrain is exposed, so plan visits during daylight and bring appropriate clothing for changeable Welsh weather.

The stone positions align with the summer and winter solstices, marking sunrise and sunset at those critical times in the year. Archaeological surveys found seven stone pits indicating where all eight original menhirs were once positioned in the ground.
