Enniskillen Castle, a former stronghold of the 16th-century Maguire chieftains, guards the western end of the town's central island, its twin-turreted Watergate looming over passing fleets of cabin cruisers. Within the walls you'll find the Fermanagh County Museum , which has displays on the county's history, archaeology, landscape and wildlife.
The 15th-century keep contains the Royal Inniskilling Fusiliers Regimental Museum , full of guns, uniforms and medals, including eight Victoria Crosses awarded in WWI; it's dedicated to the regiment that was raised at the castle in 1689 to support the army of William I. Much of this facility was refurbished in 2015.
