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 1707–1708. 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. ==Lookout towers==
