Grianan Ailigh Info | Donegal Coast

The Grianan of Aileach is a hill fort on Greenan Mountain at Inishowen in County Donegal.

The main structure is a stone fort, thought to have been built in the 6th or 7th century although there is evidence that the site had been in use before the fort was built. The wall is about 4.5 metres (15 ft) thick and 5 metres (16 ft) high, inside it has three terraces linked by steps, and two long passages within it.

Just outside the fort are the remains of a well and a tumulus.
