The five arches of which it is made up rest on columns with lavish Corinthian capitals. Friezes of fine sculptures follow the line of the architecture. An impression of richness, almost of luxuriance, is created using very sober means. The exceptional interest of Rasafah lies elsewhere, therefore. The chipped cornices, the edges of the acanthuses or of the sculpted rosettes, the carved or broken blocks, all have the glint of rose crystal.

The tow of arches creates an effect of alternating light and shade and the whole is bathed in a rose-colored glow.

It is now no more than a pathway overgrown with grass, but lining it on either side there are still blocks of marble, the broken stumps of pillars and chunks of wall from the past. It is a basilican church with an apse.
