The church features Gothic Revival architecture, with ribbed vaults, pointed arches, a central nave and two side aisles of lower height.
The nave follows the basic Gothic pattern with a triforium and clerestory-like top tier.

Inspired by the national colors of Ireland, it features green Connemara marble (Verd antique, serpentine marble) and white and gold Bontticino marble.
Decorating the church are Tiffany-style stained glass windows depicting the patron saints of Ireland's 32 counties.
