Bryn Gwyn Standing Stones

These are two giant standing stones, probably two of the tallest in Wales, standing thirteen feet and ten feet tall. They are situated in a field, and actually form part of the field boundary. The stones were recorded as being part of a stone circle the 17th Century, but the circle was allegedly demolished in 19th Century, by locals looking for buried treasure.

Castell Bryn Gwyn

There is much speculation over the age and use of Castell Bryn Gwyn (White Hill Castle). It was not a hillfort, being built on flat land, but excavations in 1959-1960 discovered that the rampart and ditch were similar to hillfort defences. It may have been a Neolithic henge monument, but nevertheless, there has been a long history of occupation at the site.
