St Flannan's College

Saint Flannan's College is an Irish co-educational secondary school located in Ennis, County Clare, which takes its name from the 7th century patron saint of the Dál gCais. It was formerly an all-boys boarding school. The first co-ed class began in 2002 for First Year students. In 2003 an extension which added over 20 new rooms and extensive new facilities to the college was completed. The school had rapidly expanded since 1962, when there were some 370 pupils, 140 of whom were day boys, and only 37 teachers. By 2004, enrollment had risen to more than 1,000 students, and Staff numbers had risen to 60. In 2005, the boarding portion of the school was closed. In the 2010–11 school year there were 1,206 students. This has since grown again to 1,276 students in 2025-2026. St. Flannan's College is the largest Secondary School in Munster.
