Forts & Ruins – Dún Aonghasa (Dun Aengus)

This means Fort of Aengus and is the most famous attraction on the Islands. This magnificent fort is a semi-circular structure that rests on the edge of a high cliff rising 100 metres out of the Atlantic Ocean. This is the largest of the prehistoric ruins on the Aran Islands. The fort is about a 900 metre hike from the Visitor Centre to the base of the rise. After visiting the centre the fort is about a 10 minute climb up to reach the top. So please be sure to have appropriate footwear.

The fort consists of an inner court 50 metres across and is surrounded by a wall 6 metres high, and 5.1/2 metres thick at the base. Outside is a rampart with its accompanying “Cheval de Frise”, a defence formed by sharp-pointed blocks of limestone set closely together in the ground to deter attackers. Dún Aonghasa’s superb position and its structural perfection have prompted many experts to declare it one of the finest prehistoric monuments in Europe.

Places to see on


Aran Heritage Centre

This centre is located just beyond the village of Kilronan. The exhibits and displays take you through Island traditions such a currach (traditional boats) making, cloth making, and also explains the geology of the Island.

Dún Duchathair (The Black Fort)

This is the second and only other fort located on Inis Mór. In its glory this fort was originally larger than Dún Aonghasa, though now its remains appear much less so. It is also surrounded by a “Cheval de Frise”, and the forts outer walls reach a height of 6 metres high and 5 metres wide. On the inside there possible remains of beehive huts.

Na Seacht dTeampaill (The Seven Churches)

Despite its name these remains are comprised of two small churches and several domestic buildings. This was well-known as a place of pilgrimage in the West of Ireland in its time. The monastic settlement founded by Disert Bhreacain rivalled the St. Enda’s settlement on the east side of Inis Mór.

Ancient Christian


Teaghlach Einne (House of St. Enda)

This is a small church that takes his name from the Patron Saint of Inis Mór. The remains are half buried in sand in Cill Einne (Killeany) graveyard. This graveyard is at least 1500 years old and contains the grave of St. Enda who died around 535 A.D.

Clochan na Carraige

This stone structure is a beehive shaped hut and is the best preserved of many similar huts on the Island. These structures were used as a place of isolation and punishment for the Hermit Monks on the Island during that period.

Upon arrival to Kilronan Harbour, Inis Mór there are Bicycles for singles & families, Pony & Trap, and Mini-bus tours all available for hire. We highly suggest you pick a mode of transport and head off to explore!

Would highly recommend Bill and his team at O Brien Ferries. Very professional and friendly service. We had a great day on their boat exploring Clare.

This is the best ferry service to use in Doolin! Do not let the other two offices try to trick you on the Pier. Bill O’Briens is the only...
