Ardrossan Castle is a ruinous castle located within the town of Ardrossan, North Ayrshire on the west coast of Scotland.
The ruins currently occupying the site are the 2nd castle to have been constructed at that location. The original castle was built by the Barcley family. The current castle is believed to date back to the 13th century.
The castle was destroyed in 1648 by Oliver Cromwell and his troops. Much of the masonry used in the castle was taken to Ayr where it was reused to build the Ayr Citadel.
What remains at Ardrossan Castle is nothing more than a ruin and the buildings are in an unsafe condition. It is however a grade-A listed structure.
As well as the ruins that can be seen above ground there are also at least two underground areas that are currently locked and not accessible. One is believed to be a well and the other is what remains of the cellars. No access is possible to these areas because they have been gated and locked in the interest of safety.
Ardrossan Castle is well worth a visit to have a look around. The area also provides great panoramic views out over the west coast. You can see the Isle of Aran and Alsa Craig on a clear day.
