Brux Castle was a castle of the Forbeses, about 1.5 miles (2.4 km) east of Kildrummy, Aberdeenshire, Scotland,[1] south of the river Don.
[2] The derelict Mains of Brux is on the site.
[3] A branch of the Forbes family owned the manor of Brux from 1409 through marriage to the heiress; it was raised to a barony in 1504–1505.
The `manor house of Brux’ was referred to as a gentleman's seat in 1724.
[3] There is little evidence of the structure, although some stonework on the Mains of Brux is probably from the castle.
