Staique Stone Fort is located three miles west of Sneem, on the Iveragh peninsula. The fort is thought to have been built during the late Iron Age around 300 to 400 AD. It is at the head of a valley opening south to the sea and is surrounded by a ditch. The fort’s walls are up to 18 ft (5.5 m) high in places, 13 ft (4 m) thick at the bottom and 90 ft (27.4 m) in diameter. One of the most interesting things about the fort is that there are ten flights of steps, built in an X shape, along the circular internal wall giving access to the top of the rampart. Staigue represents a considerable feat in engineering since it was built without the use of mortar.
There is evidence that copper was excavated in the surrounding area and it appears that the fort may have been a place of worship, an observatory and a place of defense.
