About Castell Bryn Gwyn
Castell Bryn Gwyn is a historic site. Location: Llanidan, Anglesey.
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".
