Rhug

Rhug (normally Y Rug in Welsh; sometimes given the antiquarian spelling Rûg) is a township in the parish of Corwen, Denbighshire, Wales, formerly in the old cantref of Edeirnion and later a part of Merionethshire, two miles from Corwen and ten miles north east of Bala. It includes the hamlet of Bonwen. It is situated near the River Dee, under Berwyn range. About 1150, it was ruled by the Maer Du or "Black Mayor of Rhug" and later became part of the lands of the barons of Edeirnion (see Hughes of Gwerclas) who ruled from Gwerclas Castle.
