Grainn of Aileach
Stone Ringfort on Prehistoric Site
Grainán of Aileach
Grainán of Aileach overlooks Elaghmore and is about 4 miles west of Derry. It is located on the summit of an 800 ft high hill and is made up of a group of ancient monuments extending far back into the prehistoric period.
The site is dominated by a great circular, stone fortification (a cashel), which seems to date to the early medieval period. The interior of the fort rises in terraces. The steps are easily climbed and afford astonishing views of the surrounding landscape.
