The former church of the Order of the Theatines dedicated to St. Vincent, and built at the end of the sixteenth century, is now a modern auditorium of great acoustic quality, able to accommodate about 150 spectators. Of great impact is
the decorative apparatus that covers all the surfaces of the church, dated between the end of the 17th and 19th centuries: in addition to the complex system of squares that develops on the vaults and domes, there are frescoes of saints, angels and prophets, biblical and allegorical scenes by important painters, including Roberto De Longe and Giovanni Evangelista Draghi. The intervention that most emphasizes the new happy use is the wooden stage in the area destined to the altar, protected by an innovative transparent acoustic chamber that makes the Sala dei Teatini a privileged space, especially for concert activity.
