Plas y Dduallt is steeped in history and folklore. Literally translated it means the "house on the black hillside". The estate agent said the name was taken from the dark-coloured rock nearby. A local historian has ascribed a more sinister meaning to "black" whereby people would not willingly cross this land unless they had to and certainly not after dark!

For several hundred years the house was home to the Llwyds (Lloyds) who were direct descendants of Llywelyn the Great.

The house was visited by 90 architectural historians from the Vernacular Architecture Group. They arrived by steam train and were greeted by ITV Wales, Radio Cymru and the Liverpool Daily Post who covered this unusual event. An overview of the visit appears on the BBC North Wales website.
