A 12th-century bell tower and 15th-century facade, by Giovanni Battista Soria (at the request of Scipione Borghese, then the church titular) open onto a half-Mannerist, half-Baroque decoration, but which retained the ancient columns that separated the Medieval naves. You can see the Borghese coat of arms on the vault (coffered with complex shapes), and below, are some remains of the 5th-century Early Christian church.
