Enniskillen Castle, Enniskillen - 028 6632 3110 fvic@fermanaghomagh.com

The town's name comes from the Irish: Inis Ceithleann. This refers to Cethlenn, a figure in Irish mythology who may have been a goddess. Local legend has it that Cethlenn was wounded in battle by an arrow and attempted to swim across the River Erne, which surrounds the island, but she never reached the other side so the island was named in reference to her. It has been anglicised many ways over the centuries - Iniskellen, Iniskellin, Iniskillin, Iniskillen, Inishkellen, Inishkellin, Inishkillin, Inishkillen and so on.

The town's oldest building is Enniskillen Castle, built by Hugh (Maguire) the Hospitable who died in 1428. An earthwork, the Skonce on the shore of Lough Erne, may be the remains of an earlier motte. The castle was the stronghold of the junior branch of the Maguires. The first watergate was built around 1580 by Cú Chonnacht Maguire, though subsequent lowering of the level of the lough has left it without water. The strategic position of the castle made its capture important for the English in 1593, to support their plans for the control of Ulster; this was achieved by a Captain Dowdall in February 1594. Maguire then laid siege to it, and defeated a relieving force at the Battle of the Ford of the Biscuits at Drumane Bridge on the Arney River. Although the defenders were relieved, Maguire gained possession of the castle from 1595 to 1598 and it was not finally captured by the English until 1607.

This was part of a wider campaign to bring the province of Ulster under English control; the final capture of Enniskillen Castle in 1607 was followed by the Plantation of Ulster, during which the lands of the native Irish were seized and handed over to planters loyal to the English Crown. The Maguires were supplanted by William Cole, originally from Devon, who was appointed by James I to build an English settlement there.

Captain Cole was installed as Constable and strengthened the castle wall and built a "fair house" on the old foundation as the centrepoint of the county town. The first Protestant parish church was erected on the hilltop in 1627. The Royal Free School of Fermanagh was moved onto the island in 1643. The first bridges were drawbridges; permanent bridges were not installed before 1688.

By 1689 the town had grown significantly. During the conflict which resulted from the ousting of King James II by his Protestant rival, William III, Enniskillen and Derry were the focus of Williamite resistance in Ireland, including the nearby Battle of Newtownbutler.

Enniskillen and Derry were the two garrisons in Ulster that were not wholly loyal to James II, and it was the last town to fall before the siege of Derry. As a direct result of this conflict, Enniskillen developed not only as a market town but also as a garrison, which became home to two regiments.

The current site of Fermanagh College (now part of the South West College) was the former Enniskillen Gaol. Many people were tried and hanged here in the square during the times of public execution. Part of the old Gaol is still used by the college.
