From the Wikipedia article

Castell Bryn Gwyn, officially spelled Castell Bryngwyn, is a prehistoric site on the Isle of Anglesey, west of Brynsiencyn. It is a circular clay and gravel bank covered with grass, still some 1.5 metres (4.9 ft) high and revetted externally by stone walls, which surround a level area some 54 metres (177 ft) in diameter. Its name means "White Hill Castle". Since 2024, Cadw, who maintain the site, use the spelling "Bryngwyn".

Background

Visiting

Car parking is minimal but the site is accessible from the A4080 by a footpath. Another path follows the low ridge, southwest over stiles to the Bryn Gwyn stones, or northeast, past the site of the former stone circle of Tre'r Dryw Bach, some 1/2 mi to Caer Lêb where it meets a minor road with limited car parking space.
