The Christian Brothers Grammar School, Omagh (known locally as CBS Omagh, Omagh CBS, or the Brothers) is a boys grammar school in Omagh, County Tyrone, Northern Ireland. It is the largest grammar school in Omagh. It is under the trusteeship of the Edmund Rice Schools Trust (NI). History The school was founded on 14 January 1861, on Mount St. Columba. The building has since gone into other use as a retreat. A primary school, Holy Trinity (previously St Colmcille), has been the school there since. Its original headmaster was Brother John Redmond. On its first day of activity one hundred and twenty boys, all aged between five and fifteen, showed up. In 1902 an extension, a second floor to the school and a third to the brothers' house, was added. This came at the time a considerable cost of £1,200 partly financed by an £800 loan from past pupils. Operations of the school were moved to old Church, Brook Street while construction was under way. Once finished the renovations provided the school with three more rooms; one for Manual Instruction, a sixty student accommodating classroom and a room with all the necessities for Practical and Experimental Science. The school moved to is present site on Kevlin Road in 1967. In 1993, after the resignation of Brother McCrohan, the school appointed its first non-clerical headmaster, Roddy Tierney, a former pupil of the school and a teacher in the school. The Principal is Foncy McConnell who was appointed in March 2016, having been acting Principal for the previous year, and previously Vice Principal, having taught in the school since 1987. Like Tierney he is a former pupil of Omagh CBS. It is planned that by 2026, the school will relocate with five other schools to a shared campus. The other schools are Loreto Grammar School, Omagh, Omagh High School, Sacred Heart College, Omagh and Omagh Academy which will join Arvalee Special School.
