Watercolour drawing showing historical features at Gorllwyn Uchaf by the artist Falcon Hildred, 2007.
Gorllwyn Ucha is an early hall-house situated on the edge of the Snowdonia National Park. Because of its historical features, the house was first surveyed in 1953 and, in 2009, the Dating Old Welsh Houses community project commissioned tree-ring dating which dated the timbers to 1533. It belongs to a group of houses which are between hall houses and classic Snowdonian houses.
