Dún Lúiche, anglicised as Dunlewey, is a tiny Gaeltacht village perched on the shore of Lough Dunlewey in north‑west Donegal. The settlement lies in the aptly named Poisoned Glen, at the foot of the iconic Mount Errigal, and offers striking reflections of the mountain on the lake’s glassy surface. The name means “fort of Lugh”, honouring the ancient Irish god of light, a theme echoed in a modern wooden sculpture that greets visitors at the Lakeside Centre.

History & Background

Legend says the Poisoned Glen was the battlefield where Lugh slew the giant Balor, giving the glen its ominous name. Archaeologists have identified a crannóg – a fortified lake dwelling on timber piles – on the lake’s edge, hinting at early medieval occupation. The ruined early‑19th‑century church on the western shore testifies to a long spiritual tradition.

In the 20th century the village became synonymous with hand‑loom weaving thanks to world‑renowned weaver Manus Ferry. His 1940s cottage now houses the Ionad Cois Locha (Lakeside Centre), where original looms, carding and spinning equipment are preserved. The area also nurtures the hardy Dunlewey Connemara pony, once essential for navigating the rugged terrain.

What to See & Do
