Possibly founded by Syrian merchants as early as the 2nd century, the current church is largely a Renaissance construction. Its most extraordinary feature is Brunelleschi’s small Cappella Barbadori, which is adorned by frescoes by Jacopo Pontormo (1494–1557) of the Annunciation and a Deposition from the Cross, in garish reds, pinks and oranges. Note also that the Corridoio Vasariano passes right across the facade so the Medici could hear Mass like any good Christians, but without having to mix with the common folk.
