The circle was erected at the Grove (Plas Derwen), Monmouth Road, Abergavenny in 1912 for the 1913 National Eisteddfod. It was moved to the grounds of Abergavenny Castle by 1816, and possibly to another location before they were re-erected at Swan Meadows in about 2001.

The circle consists of a circle of 12 stones with 5 outliers on the north side. It is possible that originally the outliers were on the east side but Swan Meadows is too narrow to have located them there.
