Discover more about Dún Dúchathair (Black Fort)

Dún Dúchathair, meaning "black fort" in Irish, is a captivating historical site on Inishmore Island, County Galway. Perched on a rocky promontory overlooking the Atlantic, this ancient stone fort dates back to the Iron Age or early medieval period. The name derives from the dark-colored limestone used in its construction. Archaeological excavations have not been carried out at Dún Dúchathair, so its exact age and origin remain unknown. However, similarities to other stone forts on the island, such as Dún Aonghasa and Dún Eochla, suggest it was likely built between the 1st century BC and the 7th century AD. These forts are believed to have been constructed by local chieftains or kings as symbols of power, defensive structures, and places of refuge. The fort consists of a massive stone wall, up to 6 meters high and 5 meters wide, enclosing an area of approximately 50 by 27 meters. Traces of terracing and steps are visible on the inside of the wall. Within the enclosure, ruins of several stone buildings, possibly clocháns or beehive huts, suggest dwellings or storage places for the inhabitants. Outside the wall, remains of chevaux de frise, large stones set at angles, indicate a defensive obstacle. While Dún Dúchathair lacks the historical records and legends associated with Dún Aonghasa, local folklore suggests it was once occupied by a fierce warrior named Goll Mac Morna. Today, the fort offers visitors a chance to explore Ireland's rich history and culture amidst stunning coastal scenery. There is no admission fee, allowing visitors to explore the site at their own pace.
