Plas Dduallt Medieval Hall Snowdonia National Park

Plas Dduallt translates into English as ‘House on the Black Hillside’, it dates from 1560 and was built for descendants of Llywelyn Fawr, the first Prince of Wales. Oliver Cromwell is said to have stayed during the Civil War when it was the Parliamentarians base for their siege of Harlech Castle. It is without doubt one of the oldest inhabited houses in Wales.

It has featured on TV’s ‘Most Haunted Series’ and is widely held to be the most haunted house in North Wales!

The new owners commissioned Dyfi Architecture to carry out a full and detailed survey of the property and grounds and to follow up with further advice and Architectural input.

This is a truly remarkable house that is steeped in history and even has a specially preserved narrow gauge railway station in it’s grounds named after Colonel Campbell who lived at Plas Dduallt for many years.

We get to work on some incredible houses and sites.
