Gregynog is a large country mansion in the village of
Tregynon, 4 miles (6 km) northwest of
Newtown in the old county of Montgomeryshire, now
Powys in mid
Wales. There has been a settlement on the site since the twelfth century. From the fifteenth to the nineteenth century it was the home of the Blayney and Hanbury-Tracy families. In 1960 it was transferred to the
University of Wales as a conference and study centre by
Margaret Davies, granddaughter of the nineteenth century industrial magnate and philanthropist,
David Davies 'Top Sawyer' of
Llandinam.
