Chiesa di San Teodoro al Palatino

The church of Santa Maria Antiqua, built in the 5th century, is the oldest Christian building in the Forum. The interior of the church is decorated with ancient Byzantine frescoes, dating from the time of Popes Martin I (649-655), John VII (705-707) and Zechariah (741-752). It contains the oldest representation in Rome of Santa Maria Regina, the Virgin Mary as Queen, dating from the second century.

The church of San Giorgio in Velabro was founded in 685, rebuilt in the 9th century on the initiative of Pope Gregory IV, and enlarged in the 11th century with the remodelling of the portico and the addition of the present five-storey bell tower. The large fresco on the apse's conch is attributed to Pietro Cavallini in the 13th century. In the 20th century, the church was radically restored to its early medieval, even paleochristian, appearance by Antonio Muñoz, Superintendent of Monuments in Rome, between 1923 and 1926. Since 1939, it has been administered by the Canons Regular of the Holy Cross.

Santa Maria della Consolazione was built between 1585 and 1600 by Martino Longhi the Elder in the Baroque style. It is the church of the Roman Capuchin monastery. The church is known for its frescoes and other works of art.
