Colaiste na Trionoide in Dublin centres on a historic campus and a celebrated Old Library where the Long Room turns scholarship into space – and atmosphere.

Established in the late sixteenth century as a college of the University of Dublin, it has grown into a layered ensemble of squares, gardens and academic buildings that chart Ireland’s architectural and intellectual history.

Squares, stone and a campus shaped over centuries

Parliament Square and Library Square form the western portion, framed by eighteenth-century buildings such as the Chapel, the Examination Hall and the Old Library, and this side of the campus preserves a classical layout with stone fronts and arcaded ground floors.Parliament Square and Library Square To the east, later buildings for science and engineering extend the grounds towards Pearse Street, demonstrating how the college expanded beyond its original grid into a broader urban campus.buildings mostly for Science
