The design of the façade is of the simplest: it is an angle sharp as the gable-end of an ordinary house and bordered with marble lace, resting upon a wall without any fore-part, of no distinct order of architecture, pierced by five doors and eight windows and striped with six groups of columns with fillets, or rather mouldings which end in hollowed out points surmounted by statues and filled in their interstices with brackets and niches supporting and sheltering figures of angels, saints, and patriarchs.
