The loggia of the Torre del Mangia, Siena
The marble loggia at the base of the tower where it meets the Piazza del Campo, known as the Cappella di Piazza, was added in 1352 to fulfil a vow to the Holy Virgin by Sienese survivors of the Black Death. The corner pilasters attained their current form in 1378, the sculptures decorating them being executed in 1378-1382 by Mariano d’Angelo Romanelli e Bartolomeo di Tommé. The simple wooden ceiling once covering the loggia was replaced by the current Renaissance marble vault in 1461-1468 by Antonio Federighi, also author of the bizarre decorations of the coronation. In 1537-1539 Il Sodoma painted a fresco above the altar, now housed in the town museum in the Palazzo Pubblico.
