County Hall, Coleraine

Coleraine Castle was a castle situated at Coleraine, County Londonderry, Northern Ireland. The Annals of Ulster reports that the Earl of Atholl, Thomas fitz Roland, built the castle in 1214. It was later destroyed by Hugh de Lacy and the King of Tír Eoghain, Aodh Méith Ó Néill, as evidenced by the same source in 1223.The Annals of Ulster also reports that Thomas reconstructed the castle in 1228. There is evidence to suggest that Thomas may not have been in any position to carry out reconstruction efforts. In 1225, he was owed an annuity of 100 marks in compensation for his Irish losses. In 1227, he declared that he had been impoverished through serving the English Crown in Ireland. If it wasn't Thomas was reconstructed Coleraine Castle, it is possible that Hugh did. However, the only record of Hugh operating in Thomas' lands occurs almost two decades later, in 1241.

Killowen Castle (Irish: Caislen Cill Eoghain) was a castle situated in the parish of Killowen, County Londonderry, Northern Ireland. The area was once known as Drumtarsy (Druim-tairsigh) and the castle known as Drumtarsy castle. The name "Drumtarsy" is no longer commonly recognized in the local area. Its identification has been aided by historical records, notably the Ecclesiastical Taxation, which lists the church of Drumtarssi between those of Camus and Dunhoe within the Diocese of Derry. The location of Drumtarsy Castle is uncertain. In 1213, according to the annals, English forces under Thomas mac Uchtry built a castle at Coleraine. This construction was considered a destructive event in the region, as most of the town’s cemeteries and buildings, except for the church, were dismantled to provide building materials. In 1288, a church, St. Eugene’s, was built to serve the castle and the surrounding community. The parish took its name from the church, originally known in Irish as Cill Eogain (meaning "Church of Eugene"). Over time, this name was anglicised to Killowen. The area was commonly referred to as "the Castle-side of the river." However, as Drumtarsy Castle deteriorated and was eventually demolished, the name lost relevance. The area later became known as the Waterside. In the mid-13th century, the English crown concentrated its efforts on consolidating control over Ulster and Connacht. The death of Aed O’Neill in 1230 triggered a dynastic struggle within the Cenél Eóghain weakening their resistance to external forces. Donal Mac Lochlainn, with support from the Anglo-Norman administration in Dublin, initially subdued rival O’Neill claimants but was killed in 1241 at the Battle of Camergi, an unidentified site in County Tyrone, by Brian O’Neill, allied with the O’Donnells of Tír Conaill (modern-day County Donegal). Exploiting this instability, John FitzGeoffrey, Justiciar of Ireland under King Henry III, launched a campaign in 1248 to assert royal authority in Ulster. He conducted an eyre, likely reorganizing the province’s administration, and constructed a bridge across the River Bann at Coleraine. Crucially, he built a castle on the west bank of the Bann at Killowen, establishing a fortified base for military operations. From this position, FitzGeoffrey advanced against the Cenél Eóghain, who surrendered hostages and made peace. He later extended his campaign by building another castle at Magh Cobha (modern Ballyroney, County Down), enabling further incursions into central Ulster, reaching as far as Armagh. Drumtarsy Castle remained in use into the late 14th century. In 1382, John Rynaux, Treasurer of Ulster, was ordered to repair the castle, along with the bridge of Coulrath (modern-day Coleraine) and the towers located on either side of the bridge.

Coleraine Academical Institution (CAI and styled locally as Coleraine Inst) was a voluntary grammar school for boys in Coleraine, County Londonderry, Northern Ireland. Coleraine Academical Institution occupied a 70-acre (28 ha) site on the Castlerock Road, where it was founded in 1860. It was, for many years, a boarding school until the boarding department closed in 1999. It was one of eight Northern Irish schools represented on the Headmasters' and Headmistresses' Conference (HMC). The school had an enrolment of 778 pupils, aged 11–19, as of 2012. The school was generally regarded for its high academic standards and extensive sporting facilities, including 33-acre (13 ha) playing fields, indoor swimming pool, boathouse, rugby pavilion, sports pavilion and gymnasium. The school has an extensive past pupil organisation, "The Coleraine Old Boys' Association", which has several branches across the world. Coleraine Inst was nine times winner of the Ulster Schools Cup, the world's second-oldest rugby competition, in which it competed every year since 1876. The school origins and land are tied to the Worshipful Company of Clothworkers, one of the Livery Companies making up the City of London Corporation.As part of a general re-organisation of schools in the Coleraine area over a number of years, Coleraine Academical Institution was merged in September 2015 with Coleraine High School on Coleraine's Lodge Road and became a fully boys' and girls' grammar school called Coleraine Grammar School.
