The neo-Baroque façade at the back of the church looks like the main entrance, especially as it faces onto a little piazza which is now neatly paved with sanpietrini. This portal is for looks only as it will not give access to the church. The fabric is in travertine, and has two storeys. The composition is off center, leaving a screen wall to the left which reaches the full height and has banding in grooves.
