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.

  • 3000 year old fort with incredible views! loved the hike, the view, darling little shopping and lunch spot as well!  more »
  • Well worth seeing, and definitely #1 on the Island. A stiff walk up - bring good shoes - with long views from the top. Hard to believe it has been there since 11 BC.  more »
