The best thing in the church is the monument on the left, the memorial monument to Rodrigo de Sylva and his wife Beatriz de Silveira, designed by Bernini. It also has a bas-relief framed in red jasper and surrounded by a black marble cloth, but the tondo on top has a portrait bust not a relief. The two allegorical females are Charity to the left, and Truth to the right. Both are bare-breasted, and Charity is giving her own voluminous mammaries a squeeze while smiling. The frescoes behind the monuments are by Giacinto Gimignani.
