Caer Leb

Caer Leb is a prehistoric site to the west of Brynsiencyn. Caer Leb means “Leavens Castle” This is a low lying site with a double row of pentangular banks and marshy ditches. The original entrance was on the eastern side, other gaps are more modern and have been created by livestock.

Caer Leb at Brynsiencyn on Anglesey is unlike many of the other ancient monuments.

This defended settlement is thought to be from the Iron age period around the 2nd century B.C. based upon similar enclosures around Anglesey.
