According to tradition, the San Marziale Church was built where the tomb of Austriclinian lay, who was brought back to life by Saint Martial of Limoges and became the patron saint of Colle Val d'Elsa. The entrance, raised up from the street, bears a nineteenth-century loggia, where a marble bust of Giovan Battista Schmidt stands, a Bohemian glass industrialist in the 1800s, who contributed to the development of the glass (and later crystal) industry, the pride and joy of Colle Val d'Elsa. Inside, on the main altar, there’s a seventeenth-century Florentine school painting by Giovan Pietro Benini, which depicts Saint Martial performing the miracle. There’s also a fresco, perhaps by Del Vecchietta, showing the multiplication of the loaves and Jesus meeting Zaccheus. On the side walls, we see a Saint Michael, perhaps dating to the eighteenth century, and two polychrome wooden statues depicting Saint Martial and Anthony the Great.
