Built during the city’s most flourishing period as a Free Commune (late 1100), this is the oldest existing municipal building in Lombardy. Several changes were made under the Venetian Republic’s rule, such as the reversal of the front from Piazza Duomo to Piazza Vecchia, along with its complete reorganisation. Even the entry staircase, which leads up to the Salone delle Capriate, was built in the mid-1400s.
