The exterior of the choir, with its four radiating chapels, its jutting cornices supported by modillions and columns with carved capitals, and its mosaic decoration of black and white stones, is the most interesting part of the exterior The rest of the church comprises a narthex surmounted by a tower, three naves and a transept, over which rises another tower.
The general construction of wooden screens is close panelling beneath, on which stands screen-work composed of slender turned balusters or regular wooden mullions, supporting tracery more or less rich with cornices, crestings, &c., and often painted in brilliant colours and gilded.
Above this comes a row of circular shields, adorned with intricate arabesques, while bands and wreaths of lilies are everywhere scupltured on the windows, balconies, tambours and cornices, adding lightness to the fabric. The whole is raised on a platform 7 ft.
Flatness and lack of deep shadows, owing to the impossibility of obtaining heavy cornices in that material, mark the style.
Nearly all the stucco-fronted brick houses, with flat roofs and cornices and wide spreading stoeps, of the early Dutch settlers have been replaced by shops, warehouses and offices in styles common to English towns.
