San Martino, Siena
San Martino is a Roman Catholic church on Via del Porrione in central Siena, Tuscany, in the Terzo San Martino district named after the church. Next to it is the Renaissance Logge del Papa, built in 1462 by order of Pope Pius II Piccolomini. A church has stood on the site since the 12th century, but it was rebuilt and enlarged in the 16th century. The Baroque façade was completed in 1613, and the bell tower was finished in 1738.
Inside, the counterfaçade holds a painting of the Immaculate Conception Protecting Siena during the 1526 Battle of Camollia by Giovanni di Lorenzo, commissioned by the city in 1528. The chapels include the Circumcision of Jesus, one of Guido Reni’s masterworks; the Martyrdom of San Bartolomeo (1637) by Guercino; and a Nativity by Domenico Beccafumi. The presbytery was restored in the 17th century with patronage from the de’ Vecchi family, who commissioned decorations to the Mazzuoli family. Giuseppe Mazzuoli completed the statue of St. Thomas of Villanova and helped his brother Giovanni finish the main altar.
