Saint Macartan's College — Monaghan

U-plan former seminary, built 1840-8, to designs by Newry architect Thomas Duff. Seventeen-bay front facade comprising five-bay three-storey middle block with shallow three-bay pedimented breakfront, flanked by recessed five-bay two-storey blocks, in turn flanked by single-bay three-storey projecting ends, latter forming south ends of thirteen-bay north-south lateral blocks. Lateral blocks are of two phases, six bays to south end of each terminated at original north end by canted bay, and having six-bay additions dated 1908 to north ends designed by Belfast architect John O'Donnell. Later part of eastern block is slightly higher three-storey and includes projecting five-stage tower, and western is two-storey. Lower floors of south end of west block are chapel. Other rear elevations have single-storey lean-to extensions, catslide and other projections, all fronting onto stone-paved and lawned courtyard enclosed at north by tall limestone boundary wall with wrought-iron gates. Pitched slate roofs throughout, with black clay ridges, skewed stone-capped gables on carved kneeler stones and stone chimneystacks having oversailing courses to both party walls of central five-bay block and to north end walls of lateral blocks and at canted bays where lateral blocks originally ended. Sprocketed, almost pyramidal slate roof to tower, having tall clay finials and circular louvred openings to topmost stage. Cast-iron half-round rainwater goods held by wrought-iron brackets above stepped ashlar stone cornice with moulded brick cornice to rear, later part of east lateral block, and plain brick cornice to rear of western. Squared, dressed rubble limestone walls to main facade of building with rusticated block-and-start ashlar quoins, projecting square first floor sill course, platband separating ground and first floor levels, stone voussoirs to heads of openings and projecting ashlar plinth with overhanging stone capping. Carved marble date-stone inscribed:'A.D M.DCCC.XL' with cross to bottom line, in moulded circular surround forms oculus of pediment which, along with side bays of main five-bay entrance block, also has broad ashlar platband beneath cornice. Block-and-start brick surrounds to side and rear elevation openings with finer, redder brick to rear northern halves of both side ranges and more coarse brick surrounds to front halves. Rear halves of side ranges have no stone embellishments except plain block-and-start quoins and quatrefoil date stone inscribed 1908 to rear gable apex of east range which also has quarry-faced stone as distinct from sparrow-pecked finish to masonry on other elevations and features segmental pointed brick relieving arches over second floor openings to its north end elevation.
