Housing live performances and events, the chapel was decorated with frescoes by Benedetto Biancolini, who made the building become cozy and elegant at the same time. The stage has a peculiar shape, a hemisphere. It offers the audience musical performances with clean and powerful sound. Housed in the Collegiate Church of Saint Stephen, the chapel is a real hidden treasure: a great little eighteenth-century jewel, built by the peasant religious congregation named Congregazione dei Contadini, and consecrated to the Purification of Mary.
