Cessnock Castle is a 15th-century keep greatly enlarged into a baronial mansion, about 1 mile (1.6 km) south east of Galston, East Ayrshire, Scotland, and 0.75 miles (1.21 km) south of the River Irvine.
[2] Since the mid 1990s it has been owned by the Cogley family, who reversed decades of neglect, and acquired other significant local land holdings.
[1] The massive keep, which stands in a ravine of the Burnanne has three storeys, and an attic, to which a large mansion has been added, making the building U-plan.
A painted ceiling dating from the late 16th century remains in the great hall in the newer part.
[2] The New South Wales Hunter Valley town of Cessnock was named after the castle when it was settled in the 1820s.
