Castell Bryn Gwyn (also spelledCastell Bryngwyn) is aprehistoric site on theIsle of Anglesey, west ofBrynsiencyn. It is a circular clay and gravel bank covered with grass, still some 1.5 metres (5') high and revetted externally by stone walls, which surround a level area some 54 metres (177') in diameter. Itsname means "White Hill Castle".[citation needed]
The original use of this site is uncertain although it may have been a religious sanctuary. LaterNeolithic pottery indicates use in this period, and it may have been ahenge monument at this time. The earliest bank and ditch belong to the end of the Neolithic period (2500-2000 BC).[1][2][3]
During the Iron Age, the present wall was built, and it was rebuilt in Roman times and later.[4]
Car parking is minimal but the site is accessible from theA4080 by a footpath. Another path follows the low ridge, southwest over stiles to theBryn Gwyn stones, or northeast, past the site of the former stone circle of Tre'r Dryw Bach, some ½ mile (800 metres) toCaer Lêb where it meets a minor road with limited car parking space.[citation needed]
