Dominating the southern side of Tito Square is the imposing Praetorian Palace, which has served as the municipal seat for some eight centuries. Its Venetian Gothic design dates from the middle of the 15th century, with the outer staircase and balustrade added fifty years later, and the overall appearance of the façade taking shape in 1664 after significant renovations. After serving various purposes following the downfall of the Venetian Republic at the hands of Napoleon in 1797, the building underwent a decade long restoration in the 1990s and now once again serves as the municipal seat and mayor's office, as well as the Tourist Information Centre.
