[2] The stonework was restored and the golden weathercock was added by HA Patton & Partners in 1975.

The polished granite pillars around the front courtyard had lost some of their elaborately carved sandstone capitals, but these were restored in 2000.

[3] The building has a mixture of styles, principally Italianate with a spire on top of a campanile.

[1] It has been described as one of Ulster's best High Victorian church designs – a triumph of eclecticism, where the combination of apparently discordant elements such as a Renaissance arcade with chunky Venetian columns, mediaeval machicolations, a classical cornice and balustrade, a Moorish well canopy and a French needle spire are all absorbed into a coherent but very elaborate Irish version of a Lombard Gothic church (Irish Builder).

[4] Behind the polychrome freestone façade, the interior is surprisingly large, having a great width uninterrupted by roof supports, and a deep gallery running back over both vestibule and loggia, reached by a winding staircase beneath the tower (which, while part of the 1859 design, was added in 1872).
