Place & story

Island and stronghold

Lewis’s 1837 account connects Enniskillen’s name with the island on which it stands in Lough Erne, and records Inniskillen as an older spelling. He describes a Maguire stronghold before the development of the seventeenth-century town. Island, castle and town are therefore related but distinct subjects. The defended site had an importance that preceded the later streets, corporation and county institutions. [2]

Planning a county town

The directory describes a 1612 grant to William Cole containing conditions for houses and burgesses, a church and churchyard, a market house, school, common ground and prison. Such a list reveals the intended structure of a settlement as clearly as a map might. The prison provision also connects the project with the government of the wider county. This was a planned civic centre as well as a place selected for its military position. [2]

People & connections

Cole and the supposed water gate

William Cole became constable of Enniskillen Castle in 1609. He enlarged its accommodation and completed the twin-turreted building now called the Watergate by 1614. Its familiar name can mislead: the museum reports that excavation found no evidence that it functioned as a gate to the water, and that nineteenth- and twentieth-century Ordnance Survey maps called it the old castle in ruins. A stone-lined well inside reflects the practical needs of occupation. Cole's building belongs to the Plantation transformation of an earlier Maguire stronghold. [3] [4]

A changing riverside

The attractive riverside garden has also served less picturesque purposes. The museum records that this ground was enclosed when the castle became a military barracks in the late eighteenth century. By 1842 a privy block stood at the Watergate's base; from about 1893 the garden area served as a short rifle range, continuing into the 1950s. The present setting therefore contains traces of domestic, military and recreational uses. Reading the towers and green space together gives a fuller history than treating the castle simply as a scenic backdrop. [5]
