The circle was erected at Flagstaff Hill, Bae Colwyn in 1909 for the 1910 National Eisteddfod. It consists of a circle of 12 stones with 2 outliers. 

"Extensive preparations have been made at Colwyn Bay for the ceremony of the proclamation of next year’s National Eisteddfod of Wales, which has been fixed for Tuesday, the 7th of September. The Archdruid Dyfed is to superintend the ceremony, and among the bards who are to take part are Cadfan, Eifionydd, Gwynechl, Arlunydd Penygarn, Penllyn, Bwlehydd Mon, and others. In the morning a procession is to be formed at the Colwyn Bay Town Hall made up of representatives from the principal towns of North Wales and bards and literati from, various parts. The procession will proceed through the principal streets of the town to the flagstaff, where a permanent Gorsedd has been formed through the generosity of Mr W. Whitehead, J.P. The selected stones of the Gorsedd circle represent places of historic interest in the district. The site of the Gorsedd stands on one of the most beautiful hills in the Principality. The Archdruid will open the Gorsedd at 11 o’clock, in accordance with the ancient rites of the bards of the Isle of Britain. Eos Dar is to be the pennillion singer". Cardiff Times, 4 September 1909
