Dunluce is one of the most photographed buildings in Northern Ireland and it deserves it. The ruins of the castle cling to a sea stack with the Atlantic on three sides, and the connection to the mainland is by a narrow bridge that has replaced a succession of earlier crossings. The history is genuinely dramatic: the castle changed hands repeatedly between the MacDonnell clan, the Scottish crown, and the English, and served as the seat of the MacDonnells at the height of their power in the 16th century.
The kitchen-falling-into-the-sea story is likely embellished but the structure's relationship with the cliff edge is real enough. Entry is a few pounds and includes a small exhibition. Go in the morning before coaches arrive from the Giant's Causeway tours, when you can walk the ruins without crowds. The cliff view from the gatehouse back towards the mainland is the one to photograph.
