Work will start in the autumn on the site of Northern Ireland's first shared education campus for Catholic and Protestant children.
Education Minister John O'Dowd has announced the start of preliminary work on phase one of the Lisanelly Shared Education Campus in Omagh, calling it a "critical milestone".
More than £14m in funding has been allocated for the first stage of developing the 126-acre former Army barracks site. The campus will accommodate up to six schools with 3,700 pupils.
Phase one of the work will include a site clearance to start in the autumn. Construction on a new, permanent school for Omagh's Arvalee School and Resource Centre – which was largely destroyed in a fire last year – will start in summer 2014.
