The first impression one receives on entering the building from the south door is one of size - the effect is almost that of a small cathedral. The nave is 92 feet long with the chancel extending a further 38 feet. The height of the nave is 63 feet and the width of the building, 58 feet.

The moulded ribs of the roof of the nave and side aisles are worthy of examination as each beam is painted to fit in with the overall plan of decoration.

The floors throughout the building are laid with fine mosaic in which are set many Christian symbols. The file of Apostles in the chancel mosaics are specifically based on examples from Ravenna. For the floor mosaics, the exemplars are likely to be 5-6th century Roman and Venetian. It is said that all known symbols of Christian art can be found in this building, and the visitor needs to spend a little time in exploring, for symbols are to be found in walls, floors, ceilings and woodwork.
 

Originally, the church was lit by means of gasoliers suspended from the nave arches. Made of bronze, these took the form of openwork baskets of acanthus foliage, tipped with eight gas jets (replaced in 1891 by electric light bulbs). They were unfortunately scrapped in the fifties in favour of flood lighting. In these modern enlightened times, it is nice to imagine that they would have been left – supplemented by the modern equipment. It is said that the heat from the gasoliers contributed considerably to the warmth of the church!
