The stairs consist of two transverse upper flights meeting at the top of a longitudinal lower flight. There is an internal loggia, and the first storey frontage has four gigantic Doric pilasters supporting an entablature. In between these are five arches, with their own imposts, leading into the loggia. The central one is slightly wider than the others, with its arc decorated with volutes enclosing laddering and with a scallop shell on top. It has a statue of the Madonna and Child in front of it.
