Colaiste na Trionoide in Dublin is a university college founded in 1592 that grew from a single quadrangle into a self-contained campus of courts, lawns and libraries spanning several centuries of architecture. Its historic grounds sit beside College Green, forming an enclosed world of stone and brick at the edge of the city’s commercial streets.

Colaiste na Trionoide was created by royal charter in 1592 on a site provided by Dublin Corporation, reusing the former Priory of All Hallows on land east of the medieval city walls.created by royal charter in 1592 The college grew as the sole college of the University of Dublin, becoming a long-established centre of learning attached to this historic institution.sole college of the University of Dublin

Classical courts, the Campanile and the Rubrics
The western part of Colaiste na Trionoide’s campus is marked by eighteenth-century classical buildings including a Printing House, a West Front and a Dining Hall that give the quadrangles a formal, symmetrical character with stone colonnades and pedimented facades.Printing House, West Front and Dining Hall These structures stand alongside the Chapel and Examination Hall, associated with the English architect Sir William Chambers, whose designs contribute to the ordered appearance of the college’s western courts.Chapel and Examination Hall
