Fort Augustus Abbey Church

Fort Augustus Abbey Church is an east-west oriented church located to the south of the monastery and school, connected by a short East Cloister designed by P. P. Pugin in 1880 and a Chapter House, likely also by Pugin, from 1896. The church was primarily designed by Reginald Fairlie in two phases, the first from 1914 to 1917 and the second from 1949 to 1958. The first phase includes the monks' choir with north and south aisles, a Blessed Sacrament chapel at the southeast, and St Andrew's Chapel from 1893, designed by Pugin, at the southwest. The second phase added further north and south aisles, a narthex, and a west porch with a baptistry designed by Charles Gray in 1966. The interior was completed in 1980 by W. W. Allan.

The church is a tall rectangular building with a gabled center flanked by flat-roofed aisles, all constructed from varied colored squared granite with tooled granite dressings. The north elevation features six long, narrow round-headed windows, with a similar single window at the center of the west gable, which is fronted by a gabled narthex and porch, along with a semi-circular glazed baptistry projecting to the north. Inside, the church showcases Romanesque detailing. The monks' choir features three-bay arcades supported by high round pillars and round-headed arches, a clerestory, and a timber hammer-beam angle roof. The choir is separated from the aisles by a simple parclose screen, and the plain semi-circular apse is pierced by an orange glazed cross and upper lights. The high altar is raised on a podium between the monks' choir and the nave, which is divided from the north and south aisles by octagonal pillars of Covesea stone that rise to round-headed arches, with plain white walls. The Blessed Sacrament chapel at the southeast, built in 1917, has an altar beneath a richly embossed deerskin baldachino supported by painted facetted columns designed by Fairlie. The timber ceiling features moulded joists, and the podium and flooring throughout most of the church are laid with varied green Coniston slate.

In 2012, the Abbey Church was converted into residential and holiday apartments, with further developments completed in 2019.
