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.

  • As we stayed overnight at Kilmurvey House our admission fee was waived. The walk up to the hill fort was quite at 10.30, as the ferry crowds hadn't got there yet! Impressive remains, well worth the...

  • Beautiful views and interesting site, I belive you can buy a guidebook if you are interested in the history and information as there are no signs or info graphics. I prefer this as it preserves the natural beauty. Warning to anyone with accessibility needs the site is not accessible it is quite a climb up rocky terrain. Definitely recommend going early (before 12) to avoid the crowds.
  • Fascinating cliffs, with possibly even better views than their larger counterpart on the Irish mainland due to the lack of fence. You can sit on the edge if you’ve got stomach for it. Unfortunately we were in a bit of a hurry and didn’t have much time to learn about the history of the place, which can only add to the experience so be sure to leave about an hour for this place.
