Nantclwyd y Dre

Carbon dating of the timbers of the house have shown that the core structure was started in 1435/1436. This dates the property to the time after the destruction wrought by the army of Welsh prince Owain Glyndŵr, and the English-sponsored rebuilding of the affected Welsh towns. In the 15th century Ruthin was a regional centre for weaving, and the land on which the house now stands then belonged to Welsh weaver Goronwy ap Madog and his English wife Suzanna. The name Nantclwyd y Dre was probably bestowed on the property in the 1720s.

The distinctive porch on stilts with chamber above was added to the original mediaeval street frontage in about 1693 by Eubule Thelwall, as was shown by tree ring dating of four samples. There is a fine surviving monument to Thelwall in Llanelidan Church. At the same time he built Nantclwyd Hall; the land was acquired through his marriage to the Parry heiress.
