The first Enniskillen castle was built on this site by Hugh Macguire in 1428. It featured greatly in Irish rebellions against English rule in the 16th century and was taken after an eight-day siege in 1594. Captain William Cole remodelled and refurbished the castle adding the riverside tower at the south, known as the Watergate, in 1609.
The castle was remodelled as “Castle Barracks” as part of the response to a threat of a French invasion in 1796. Castle Barracks became the home of the 27th Regiment of Foot in 1853. The barracks continued to be used by other regiments and, from November 1939, they became to home of the North Irish Horse, a Territorial Army unit.
The barracks were decommissioned in 1950 and were converted for use as council depot. The castle was subsequently opened to the public as a heritage centre.
The castle consists of two sections, a central tower keep and a curtain wall which was strengthened with small turrets called Bartizans. The design of the castle has strong Scottish influences. This can be particularly seen in the Watergate, which features two corbelled circular tourelles which were built about 1609.
The castle is now home to the Fermanagh County Museum, which focuses on the county's history, culture and natural history. Exhibits include the area's prehistory, natural history, traditional rural life, local crafts and Belleek Pottery, and history of the castle. It also contains information on the Maguire family. The castle also houses the Inniskillings Museum, which is the regimental museum of the Royal Inniskilling Fusiliers and the 5th Royal Inniskilling Dragoon Guards.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
