 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.
