Enniskillen Castle

Enniskillen Castle is a historic castle in the town of Enniskillen, County Fermanagh, Northern Ireland, dating to the late medieval period and now housing museum collections.

The site contains museum displays covering local archaeology, social history and the military history of the Inniskilling regiments, arranged in rooms within the castle complex. Visitors can walk the castle courtyards and view the riverside setting where the River Erne narrows between Lough Erne’s upper and lower basins.

The castle originated in the late medieval period as a defensive stronghold and later saw military activity and garrison use in subsequent centuries. Over time it transitioned from a fortification to a civic and cultural site that now accommodates museum collections and public exhibits.

Located in the centre of Enniskillen town, the castle occupies a strategic riverside position on the River Erne in County Fermanagh, Northern Ireland, close to the town’s main streets and waterfront.

• Positioning: Sited on a rocky promontory where the River Erne narrows, offering views over the river and easy access to both town and waterfront.
• Dual museums: Combines historic architecture with two museum collections that document both local history and the region's military past.
