Bryn Bras Castle

Bryn Bras Castle is a Grade II* listed country house located on the old road between Llanrug and Llanberis known locally as the Clegir road, in Caernarfon, Gwynedd.

It was built in a neo-Romanesque style between 1829 and 1835 on the site of an earlier structure by architect Thomas Hopper for Thomas Williams (1795-1874), an attorney at law.

It was bought in 1897 by Capt. Frank Stewart Barnard, High Sheriff of Caernarvonshire for 1903-04, who stayed at the castle until his death in 1917, running it as a stud. It was later owned by the oil millionaire Duncan Elliot Alves (1870-1947), who was Mayor of Caernarvon for six years and High Sheriff of the county for 1931-32. After Alves' death in 1938 the estate changed hands a number of times and much of the surrounding land sold off.

The site of the first motorcycle Dragon rally in 1962, the house has been converted into luxury holiday apartments.
