Santa Maria in Traspontina is a Carmelite church. The shrine lies on the Via della Conciliazione. The current Cardinal Priest of Santa Maria in Traspontina is Archbishop Marc Ouellet. Pope Alexander VI demolished an ancient Roman pyramid on the same site (the Meta Romuli, believed in the Middle Ages to be Romulus's tomb, and portrayed on the bronze doors to St Peter's Basilica and in a Giotto di Bondone triptych in the Vatican Museums) for the construction of the first church. This church was then demolished during the pontificate of Pius IV (1559–1565) to clear the line of fire for the cannons of the Castel Sant'Angelo, who wished to exercise shooting on the Gianicolo Hill.
