Flemingston can be found to the south of Cowbridge, and to the north of St Athan in the Vale of Glamorgan, South Wales. Flemingston sits in the heart of Glamorgan and is visited by many while walking the Vale of Glamorgan Heritage Trail.

It is famous for being the hometown of Welsh antiquarian, and literary forger, Edward Williams. It is where he made his home, where he raised his children, where he dreamed of Glamorgan's Romantic and druidic past, and where he composed many of his letters, poems, essays and literary forgeries. Indeed, letters were sometimes addressed to him at the 'Bardic Lodge, Flimston'. His home stood on the site of present-day 'Gregory Farm' and a rough sketch of Iolo's cottage (in his own hand) survives.

From an early date he was concerned with preserving, and maintaining, the literary and cultural traditions of Wales. In London in 1792 he founded the Gorsedd, a community of Welsh bards, at a ceremony on Primrose Hill. Never letting the facts get in the way of a good story and using his talents in the art of deception to the full, Iolo Morgannwg as he became known, organised the proceedings, which he claimed were based on ancient druidic rites. Surprisingly there are many followers of Morgannwg among Wales' “great and good” to this day. Edward Williams, or Iolo Morgannwg as he became known, died in 1826, with little money to his name.
