The grounds of the college are accessed primarily from a tree-lined avenue on the Antrim Road, which leads to the front quadrangle, known as "the quad". The foremost building, which comprises 3 sides of the quadrangle and faces westward, is the oldest part of the college and dates to its earliest days in the 1830s. 'A' and 'B' blocks, housing the History, Classics and Drama departments, as well as administrative offices, the library, and the chapel, take up much of these three sides; the remaining rooms consist of priests' apartments, abandoned dormitories and the Upper Study Hall. The more modern seminary building (see below) completes the fourth side of the quadrangle. The college canteen and Music block are also accessed through the front quadrangle.
