The Knights Templars built their church on this site, which was destroyed, and the present edifice was erected by the Knights Hospitallers.

It is in the Norman style of architecture, and has three aisles, running east and west, and two cross aisles.

At the western end is a spacious round tower, the inside of which forms an elegant and singular entrance into the church, from which it is not separated by close walls, but merely by arches.

The whole edifice within has an uncommon and noble aspect.

The roof of the church is supported by slight pillars of Sussex marble, and there are three windows at each side, adorned with small pillars of the same marble.
