An early Gorsedd was held by Iolo Morganwg at a location known as the Rocking Stone (in Welsh, Y Maen Chwŷf) at Pentrebach, Pontypridd; Iolo, a stonemason by trade, constructed a stone circle around the central stone. Iolo had already held a similar ceremony in 1792 in London, also featuring a stone circle. It has been suggested that the Gorse Stone, located on Stanton Moor in Derbyshire, has some connection with similar Druidic rituals of prehistoric times.
