Dunluce Castle was built by Richard de Burgh, the Earl of Ulster. In 1584 it fell to the famous battle hardy MacDonnell clan who ruled this north eastern corner of Ireland in the 16th century. In 1588 the MacDonnells used their helping of the treasures from the Spanish Armada ship the Girona, wrecked off the Giant's Causeway, to refurbish the castle. However, in 1639, during a violent storm, part of the castle fell into the sea after which it was abandoned by the MacDonnells. It has a breathtaking location perched on a cliff top along the spectacular Antrim coast.
