Dún Aonghasa is located on Inis Mór (Inishmore), the largest of the three Aran Islands – the name actually means ‘big island’ in the Irish language. The island's main hub is the village of Kilronan, where ferries from Clare and Galway arrive several times a day.
While Dún Aonghasa is its best-known attraction, Inis Mór has more than 50 different monuments from Christian, pre-Christian and Celtic eras. Stretching out terrifyingly over the sea is Dún Dúchatair, also known as the Black Fort. Erosion from the wild ocean has left the fort on a thin platform over the water so peek over the edge at your own risk!
And don’t miss Teaghlach Einne, the house of St Enda, a little church half-buried in sand at Killeany graveyard. The graveyard is at least 1500 years old, and still serves as the main burial ground for the island. St Enda himself, the patron saint of Inis Mór, is believed to be buried there.
