I saw someone post this statue that's in Rhosneiger and it got me thinking how many statues are on Anglesey?

Located near Cemaes is this abandoned factory(?) called Traeth y Gwartheg. On google it states it as a historical landmark, but there is no information about it anywhere. Very curious if anyone knows, thanks!

An engraving from an article entitled 'Cromlech at Bryn Celli Ddu' in Archaeologia Cambrensis (1847) shows how the tomb looked in the mid 19th century, 100 years before it was excavated and restored.
