Enniskillen Castle, built nearly 600 years ago on the banks of the River Erne by the ruling Gaelic Maguires, now operates as an important cultural institution housing multiple museums. The Fermanagh County Museum features seven galleries showcasing the area's history from prehistoric times through the modern era, including artifacts from the excavation of the Drumclay Crannog. The Inniskillings Museum displays a rich collection of military treasures, including personal effects, battlefield items, weapons, uniforms, medals, musical instruments, and regimental silver spanning centuries of military heritage. Located in central Enniskillen with free parking, the castle museums offer visitors comprehensive access to regional history and military tradition through carefully curated collections.
