Of the scenic Aran Islands off the west coast of Ireland, Dún Aonghasa is the most visited prehistoric fort of the area. Perched on the cliffs overlooking the Atlantic Ocean, it has become a notable place for visitors from all over the country and the world. The semi-circular stone fort dates back to the Late Bronze Age and Iron Age, offering a glimpse into a rarely seen part of history. It is named for “Aonghus mac Úmhóra,” a mythical Irish king and pre-Christian god. Its multiple ancient stone walls, stairwells, and chambers create enclosure and different layers to explore.
It is still unknown exactly when and for what purpose Dún Aonghasa was originally constructed. Part of the structure has collapsed into the sea, adding to the site’s mystery and intrigue. Aside from its archaeological and historic importance the fort offers some of the most beautiful panoramic views in all of Ireland, with spectacular sights of the coastline and surrounding sea.
Dún Aonghasa is located on the isle of Inismór in the Aran Islands and is accessible by ferry from either Doolin or Galway City. Just 7 kilometers from Kilrónan, it is also a popular destination for a bike ride while on the island. It’s open daily from 9 am to 6 pm and costs €2 for adults or €1 for students and children.
