Legend says it was built by the ancient gods; the ring fort was known as the Sun Palace and was held sacred. Traces of ancient earthworks, dating to the early Iron Age, surround the fort, enclosing an area of about 5 acres (0.02 km2). The fort itself was probably built in the early centuries of the Christian era. From the 5th to the 12th century AD it served as the royal seat of the O Neill sept of Aileach; it was destroyed by Murtogh O Brien, king of Munster in 1101. To make the demolition complete, the king ordered each of his soldiers to take away a stone from the fort. Grianan of Aileach was reconstructed by Dr Bernard of Derry in 1870, but archaeologists are doubtful about the inner restoration. Surrounding the stone fort are three concentric low walls which formed part of the original fortification of the fort.

This is a fantastic natural attraction situated on the top of a hill over looking beautiful Donegal. It is a free attraction and well worth a visit. It is about fifteen minutes drive from Letterkenny and the same to Derry.

Situated on the top of a hill and providing excellent views along the Swilly and Foyle Estuaries. Large areas of Counties Donegal, Derry and Tyrone can be seen on a good day. Walk down the path to the Holy Well

This restored stone fort is worth a detour if, like us, are heading out of Derry along N13. We had a hard time finding it at first, but just follow the brown tourist signs. The view is grand.

We made a last minute decision to wind our way up the narrow road to this ancient "fort" - and it was well worth it! Spectacular views across the Irish countryside for miles (along with a really strong wind blowing). We were able to walk...More

We didn't know about this place until a couple who shared breakfast with us at our B&B recommended it. So we stopped by and are so glad we did. It is a bit out of the way, and we received excellent directions, but still felt...More

Unusual visitor experience, wouldn't even know it was there until you drive right beside it. Worth a look if driving the Inishowen 100

Located not far from Derry, Grianan of Aileach is a restored stone hill fort commanding beautiful 360 views of the Donegal surrounding countryside. Well worth stopping off if you are touring, e.g. The Wild Atlantic Way or staying nearby.
