The busy tourist centre of Enniskillen occupies an island between Upper and Lower Lough Erne. The town gained fame for the wrong reason in 1987, when 11 people died in an IRA bomb attack, but it deserves a visit for its setting and sights. At the west end of town stands Enniskillen Castle, dating from the 15th century. It houses Fermanagh County Museum and the Inniskilling Regimental Museum. Its most stunning feature, however, is the Watergate, a fairy-tale twin-turreted tower, best admired from the far bank of the river. Further west, Portora Royal School, founded in 1618, counts among its old boys the play-wrights Oscar Wilde and Samuel Beckett.
