Craignethan Castle Castles

Craignethan Castle is a ruined castle in South Lanarkshire, Scotland.

Built in the first half of the 16th century, Craignethan is recognised as an excellent early example of a sophisticated artillery fortification,[1] although its defences were never fully tested. The castle is notable as the last purpose-built fortress to be constructed in Scotland.

Craignethan is built on an imposing site above a bend in the River Nethan. Steep slopes protect the castle on the south, north and east sides, but the castle is actually overlooked by higher ground to the west, making it far more vulnerable than it appears. Craignethan's defences are therefore concentrated towards the west. The castle comprises a low central keep, within a rectangular walled courtyard. To the west is a deep ditch and beyond, a larger outer courtyard.
