Ruins of a 15th-century Welsh hall on a wooded hillside

The ruined remains of a late-medieval Welsh hall, sitting on a wooded shoulder of Bryn Euryn just behind Colwyn Bay. Only a single tall gable wall with its great central fireplace stands intact, but the foundations of the rest of the building can be traced in the grass around it.

The site is reached by a short path from the Bryn Euryn car park and makes a natural pairing with the climb to the summit. There is no entrance fee and the ruins are unfenced, which is part of the charm — you can wander among them and try to picture the large Welsh household that once lived here. Information boards explain the building's two main phases.

A story
The current ruins are the 15th-century house of Robin ap Gruffydd Goch, but the site is much older — a court (*llys*) of the Welsh princes of Gwynedd stood here before being burned in 1409. Robin ap Gruffydd's hall replaced it, and was abandoned in turn by the 17th century, leaving the gable end with its huge fireplace that you can still walk through.
