Nannau Hall

Nannau (Welsh for 'the place of streams'') refers to both an ancient estate and its current Georgian mansion near the village of Llanfachreth, Gwynedd, North Wales. The mansion was initially inhabited by the Welsh Nanney (Nannau) family, and was in the possession of this one family for over 900 years. At its largest Nannau was 12,000 acres. Nannau is a Grade II* listed building and its parkland is listed, also at Grade II*, on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. The family dynasty was founded by Cadwgan of Nannau, identified with Cadwgan ap Bleddyn of the Lleision, a family associated with the Kingdom of Powys. The Lord of Nannau title continued for four centuries, until the division of the cadet branches. The estate was then passed on to an heiress, Janet, who married into the Vaughan family of Hengwrt in 1719. In 1795, their descendants, the Vaughan baronets, replaced the then 17th-century mansion with a new house co-designed by Joseph Bromfield, which still stands today. The head of the family represented the local county as Sheriff of Merionethshire and held the position nine times in 400 years between the 16th and 20th centuries. In 1911, as recorded by Encyclopædia Britannica, the families of county rank in the neighbourhood of Dolgellau included those of Nannau, Hengwrt (the famous Hengwrt Welsh MSS), Caerynwch, Fronwnion,
