Natural Heritage Area
Horn Head cliffs rise straight out of the water to a height of about 600 ft/180 m on the ocean side of the peninsula. They are an internationally important colony for breeding seabirds. Species include the European shag and the razorbill. It is designated as an Irish Natural Heritage Area and as a refuge for fauna specifically seabirds. Horn Head cliffs are also designated a Special Protection Area and a Special Area of Conservation by the Irish government.
McSwyne's Gun is a blow hole on the west side of the peninsula. Previously, during storms, water could be forced through it to a height of 200–300 feet with a noise that could be heard ten miles away. Although still functional, it is not as spectacular any more. Several people have been killed after getting too close and falling in.
Horn Head House
Horn Head House, or Landlord's House as it is locally known, stands on the Sheephaven Bay side of Horn Head. The Horn Head estate was bought in 1700 by Captain Charles Stewart, a veteran of the Battle of the Boyne, who commissioned William Wray of Ards to build the present house in 1701, when it was the largest house in the Dunfanaghy area. Stewart was appointed High Sheriff of Donegal for 1707–08. It remained the seat of the Stewarts of Horn Head, several of whom were also High Sheriffs, from then until 1935. It has been empty since then.
