Donegal (Irish: Dún na nGall) is a town in County Donegal, in the Province of Ulster, in Ireland. Donegal is not the county town (capital) of County Donegal, despite being its namesake. Rather, the county town is Lifford, and Letterkenny is the county's largest town. Donegal town is situated at the mouth of Donegal Bay, on the River Eske and is overshadowed by the Bluestack Mountains. The town has been bypassed by the N15 and N56 roads. The Irish name translates into English as Fort of the Foreigners (Vikings).
