The interior is elliptical. There are seven small chapels, decorated in polychrome marble. The church of SS Nome di Maria in Trajan's Forum was Derizet's most important work. Cardinal Lodovico Pico della Mirandola greatly favoured Derizet's project and imposed it on the Confraternity. Although initial drawings (Berlin, Kstbib.) show a determinedly Rococo design, with a two-storey, pedimented, curved façade, the final building was a conscious imitation of the adjacent S Maria di Loreto (begun early 16th century), with a drum over an octagonal base. The plan was a transverse ellipse, perhaps derived from Jacopo Vignola's S Anna dei Palafrenieri, Rome (1565-1576).
