Barclodiad-y-Gawres Chambered Cairn
This burial mound has five carved stones within its chamber, now capped by concrete to prevent their erosion. The stones are carved with a range of patterns including spirals cup marks and zig-zag features. The purpose of these marks is unknown, but they may have had some ritual function.
Chambered cairns were often seen as the work of giants or legendary figures, often transformed to giant size.
The opposite drawing shows a portion of the carving on one of the stones. Their meaning is elusive.
Directions: The burial chamber is situated on the Anglesey coast, on a footpath off the A4080.
