One of the most historic and scenically beautiful castles in Scotland. The castle was built about 1200. The castle was a fortress and a state prison during its 450 years history. The display inside is excellent and the castle is picturesque, but the real fun here is that you can go down a mine dug in the mid-16th century as part of the siege efforts against the castle. The castle has lots of areas to explore, tunnels and ruins. The views of the coast are spectacular from here.
