About this stretch of coast
The cliffs here are part of the Giant's Causeway and Causeway Coast World Heritage Site. The basalt columns and headlands formed from ancient volcanic lava flows. The volcanic origin of the rock was set out by Dr William Hamilton in a series of published letters in 1786, and Hamilton's Seat above Benbane Head still carries his name.
At the eastern end stands Dunseverick Castle, on a rocky headland reaching into the sea. The site has more than 1,500 years of history and began life as a stone fort placed to defend the coast against attack from the water. Only fragments of the later castle remain today.
The cliffs are also a haven for seabirds. Walkers regularly spot fulmars on the ledges, and the area is known for choughs and peregrine falcons hunting along the headlands.
