The gallery now constitutes a unique collection of Venetian paintings from the most ancient artists down to Tiepolo, one hall only being reserved for other Italian schools and one for foreign schools.
Tiepolo, followed by members of the Quirini family and many nobles with their followers, attempted to seize the Piazza on the 15th of June 1310.
Quirini was killed, and Tiepolo and his followers fled.
Erected first as a temporary committee of public safety to hunt down the remnant of the conspirators and to keep a vigilant watch on Tiepolo's movements, it was finally made permanent in 1335.
In the upper rooms is placed a large collection of Milanese and central Italian ceramics, stuffs, furniture, bronzes, ivories, enamels, glass and historical relics; together with a picture gallery containing works by Vincenzo Foppa, Gianpietrino, Boltraffio, Crivelli, Pordenone, Morone, Cariani, Correggio, Antonello da Messina, Tiepolo, Guardi, Potter, Van Dyck and Ribeira.
