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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
