The evocative Chiesa di San Pietro in Montorio, so called by "Mons Aureus", name given to the Gianicolo for its golden marl, was built before C.IX on the place where, for an accidental tradition, one thought that San Pietro was crucified. Restored right after 1481 for the command of Ferdinando IV di Spagna, probably on a plan by Baccio Pontelli, it was remodeled after the combatmens in 1849 which had partially damaged it. 

The simple and elegant Renaissance façade is traditionally attributed to Meo del Caprina but pondered to be from the School of Bregno by authoritative critics. It rises on two floors with angular pilaster strips, which close up a gothic rose-window and the portal that is accessible via a stairway with a double-ramp. 

The interior has a single nave, with four chapels per side, all originally shaped like an apse, and two wider chapels that make up the transept. In the first chapel to the right one finds the "Flagellazione" by Sebastiano del Piombo and dated 1518 on a drawing by Michelangelo. In the small courtyard of the church one finds the famous Tempietto del Bramante, round shaped, made of sixteen Dorian granite columns.
