Four gigantic pilasters of a derivative Composite order support an entablature. The frieze of the entablature has a dedicatory inscription in gilded letters. Above the entrance is a rectangular panel featuring a relief of St John the Baptist and St John the Evangelist venerating Our Lady. Above the windows are two square panels featuring hexagonal medallions decorated with ribbons. One depicts a lamb as the symbol of the Baptist, the other an eagle as that of the Evangelist.
