17th-century fort
Cromwell's Citadel walls
Stretches of wall survive from the fort Oliver Cromwell's army built at the mouth of the River Ayr in the 1650s.
Hidden gem
After the English Civil War, Cromwell's forces built a large fort beside the harbour to hold down the west of Scotland. It could house up to 1,000 troops and had the sea on two sides.
When Charles II returned to the throne the citadel was dismantled. In 1663 the land went to the Earl of Eglinton, who made it the separate burgh of Montgomerieston. That burgh was later absorbed into Ayr, and around 1800 the moat was filled in and houses went up inside the walls.
Parts of the wall still stand near the harbour and along Cromwell Road. Look for Miller's Folly, built onto one stretch of the old wall.
