Built in the middle of the 13th century, Basilica di Santa Maria Gloriosa dei Frari was extended and continued so until the 16th Century. The church houses paintings by Titian, such as l'Assunta and La Madonna di Cà Pesaro. In the side chapel, you will find Bellini's Madonna in trono. It also contains the tombs of Titian, Canova, Monteverdi, and Francesco Foscari. In spite of it's many historical and artistic treasures, the church's large dimensions make it seem empty. Services are held daily. Call ahead for details or simply walk in.
