Mussenden Temple is located in the beautiful surroundings of Downhill Demesne near Castlerock in County Londonderry. It perches dramatically on a 120 ft cliff top, high above the Atlantic Ocean on the north-western coast of Northern Ireland.

The romantic vision of Frederick Hervey, Earl Bishop of Derry, he created an elegant mansion at Downhill, which nows lies in ruins. Mussenden Temple was his circular summer library, built in 1785 in the same architectural style as the Temple of Vesta in Tivoli, near Rome.

The dramatic setting on a wild coastal headland uniquely reflects the personality of its flamboyant creator, and offers visitors clifftop walks with breathtaking views.
