Courtyards, campanile and the Long Room
Approaching from College Green, visitors step through an entrance and emerge into a paved space known as Front Square, framed by formal stone facades and dominated by a stepped bell tower, the Campanile, erected in 1853.Campanile erected in 1853 Around it stand halls such as the Examination Hall and the Chapel, whose classical details and regular windows give the square a distinctly Georgian and Victorian character.
Beyond Front Square, further courts and lawns open out, but the architectural heart of Colaiste na Trionoide lies in the Old Library, whose main building dates from the eighteenth century and houses hundreds of thousands of volumes in its timber-lined Long Room.Old Library building Inside, bookcases in dark wood run the length of the hall, interrupted by busts of scholars and lit from above, creating a monumental interior that contrasts with the cobbled squares outside.
