This is a single-naved Church with a Romanesque Gothic plan, built in the heart of the city, originally dedicated to St. Anthony and later to St. Augustine. Its interior was radically renewed in the 18th century, adapting it to the Rococo fashion. It was adorned with elegant stucco decorations attributed to the sculptor Agostino Varlè, increased in height to accommodate the Callido organ and covered once more with a barrel ceiling. The former Church of Sant’Agostino was restored in the 1990s and converted into an auditorium, a privileged place for holding art exhibitions and important cultural events. A short time later, the 19th-century paintings by Pietro Tedeschi, the artist from Pesaro, were restored, including the ”Madonna della cintura”, St. Nicholas of Tolentino and the souls in Purgatory, and the Almsgiving of St. Thomas of Villanova. The magnificent organ was also restored during the same period and is now working perfectly. It was made by the Venetian Gaetano Antonio Callido, a student of Pietro Nacchini, the highly regarded organ maker who was originally from Dalmatia. For several years now, the Auditorium of Sant’Agostino, opposite the “Marco Moretti” Municipal Picture Gallery, has provided an excellent venue for outstanding events: art exhibitions of national importance, concerts of ancient music, conferences, classical and modern dance performances and cultural events.
