Dunluce Castle is said to have inspired the royal residence in The Chronicles of Narnia, and the beautiful ruins in Northern Ireland's County Antrim really does have all the airs of a fairy tale about it.
Built in the 14th century by an Earl of Ulster, it was already in need of repair in the 16th century when a a ship from the Spanish Armada was dashed on nearby rocks and its treasure sold off to pay for restoration work. Dunluce fell into ruin a century later and it's now a picture-perfect relic of times past.
