The church floor lies six feet below street level, creating an architectural illusion of being larger internally and from the entrance there is an unimpeded view across the nave and into the chancel. Octagonal stone columns topped by brick arches separate the aisles from the nave; above these arches are a series of clerestory windows. A large series of stained windows dominates the west wall. A series of 144 painted shields adorn the nave ceiling, representing the Anglican missionary dioceses founded within 100 years of the church.
