Gilbertfield Castle is a ruined 17th-century fortress near Cambuslang, south-east of Glasgow, built around 1607 on the north slope of Dechmont Hill. The castle features an L-plan tower house with a projecting stair tower containing multiple rooms and a square turnpike stair. Its basement level was vaulted with cellars and a kitchen featuring a large fireplace and oven. The castle was home to William Hamilton of Gilbertfield (1665–1751), a retired soldier and writer known for translating Blind Harry's epic on William Wallace. Now a Scheduled Ancient Monument and category B listed building, the castle stands as a neglected ruin with only the corbelling of the north-west turret remaining after the east wall collapsed in the 1950s.
