Enniskillen Castle, situated beside the River Erne in County Fermanagh, was built almost 600 years ago by the ruling Gaelic Maguires. Guarding one of the few passes into Ulster, it has been strategically important throughout its history. Today, the historic site houses two museums, Fermanagh County Museum and The Inniskillings Museum. Enniskillen Castle closes on half day Friday 21 December 2018 at 1pm for Christmas holidays and will reopen on Wednesday 2 January 2019 at 9.30am.
