Santa Maria Antiqua (English: Ancient Church of Saint Mary) is a Catholic Marian church in Rome, Italy, built in the 5th century in the Forum Romanum, and for a long time the monumental access to the Palatine imperial palaces. Located at the foot of the Palatine Hill, Santa Maria Antiqua is the oldest Christian monument in the Roman Forum. The church contains the earliest Roman depiction of Santa Maria Regina, the Virgin Mary as a Queen, from the 6th century.
