4.8/5 based on 900+ reviews on the web
Perched atop a cliff, Dun Aonghasa represents the most popular of the prehistoric forts on the Aran Islands. Walk from the nearby museum up to the fort and enjoy panoramic views from the 100 m (328 ft) cliff. Marvel at the three terraced walls and intricate defense system of stones called Chevaux de Frise. Archeological studies have revealed that the fort was built in the Iron Age, possibly as far back as 1100 BCE, though the triple-wall defenses were likely added around 500 BCE. The fort is named for a pre-Christian god or mythical king, Aonghus mac Umhor. Explore the history of this ancient monument, but take care when walking and climbing around the site, especially with children, as it can be slippery.

  • We parked our bikes and made the trek to Dun Aonghasa. It was a wet day and it was quite slippy underfoot so I wouldn't recommend it if you're not steady on your feet. The views of the cliffs and ocea...  read more »
  • I think that this site is really the place that worth it to move on the island! It's very impressive, especially since we can go to the edge without protection attention!

  • Moderate hike up a gravel and rocky path to top. Once you get to the top, there are too many beautiful viewpoints to count. The hike can take as long or as short as you want. Highly recommend making t...  read more »
  • For those who are fascinated by prehistoric sites, as I am, this is a must-see if you visit Ireland. While there is not much known, and thus to tell, in the small museum, the sheer natural beauty of the site alone is worth the visit. It was easy to let my imagination run free, standing there among the ruins looking out over the sea. We also had a wonderful lunch in the cosy little cafe along the main road where the tour buses drop off visitors. The staff were very friendly and chatted with us, while serving delicious food (I recommend the Guiness stew).
  • My favorite place in Ireland without doubt. Well worth the hike but it's a little further up than it looks so be prepared to hike a bit.
  • Absolutely worth a visit! The whole island is beautiful, but the scenery at the fort is especially gorgeous. Even in the pouring rain it was amazing.
  • Prepare yourself for an experience like no other, a prehistoric stone fort sited on a sheer cliff on the western edge of an island in the Atlantic. Spectacular is one word that could describe one of the most important archaeological sites in Europe. It's a decent walk up to the fort so those who have mobility problems might find it tough going, but the rewards are well worth it when you can sit and look across thousands of miles of ocean. Even in July it isn't too busy but there are plenty of tourists around. Guides are also available inside the fort to answer questions etc.
  • 3,000 year old fort on the western edge of Inishmore. Worth a visit.
