From Piazza Duomo take the Calmaggiore, the most noble artery of the city, which is facing numerous palaces. The road runs beside the Campanile del Duomo and Piazza dei Signori reaches. Probably, although the debate is still open, it is cardo of the Roman Empire.
To the left of Calmaggiore (Via Cornarotta and Via Bianchetti) and right (Via Parsi Bordon) are still visible a few of the many homes built towers in the city after years Mille. These towers were built as a fortified residence of feudal families that have to locate in the city to participate in decisions military, political and economic consequences of civic community that was organized for the creation of the Free Town.
A large part of the old municipal resolutions is kept at the Library Capitolare (more than forty thousand volumes) in Via Paris Bordon. This collection, together with other stored at the Biblioteca Comunale, is the most important legislative body of a city of old town in Italy. From the library you can admire the striking image of the green domes of the Cathedral framed by the warm brick of the canonical New duecentesche.
Worthy of note is the existence of an archive at the Bishop's Curia, invaluable for the quantity and quality of material: the oldest documents date from the early tenth century.
Later, along the same route, we arrive in Piazza Pola on which overlook the one hand, the medieval Tower of canonical and other local office of the Bank of Italy.
The Calmaggiore is one of the busiest streets of the center. Many of the old houses that overlook the centuries have been several changes to forget facades and especially under the arcades with the introduction of stores that follow each other in sequence continues on both sides to Piazza dei Signori.
Along the streets that open to either side of Calmaggiore is possible that some buildings worthy of note. The Palazzo de 'Rich, for example, in Via Barbary, has a Gothic facade with triple mullioned windows and stone of Istria and fresco decorations in a pretend upholstery. Today the palace, built in typical Venetian style of the second half of the fifteenth century, hosts small exhibitions and cultural meetings. The Church of San Gregorio, in the alley, still retains the original decorative strips dating back to 1500 painted on interior walls, the blade of the Holy Holder is the work of Palma il Giovane (1544-1628); the Transit of St. Joseph is a painting by Gaspar Diziani (1689-1767): the paintings were commissioned by the School of Osti and the Byron School, which took place here.
Ancient houses painted facades or brick are also found in Alley Street and Barbary (the name seems to derive from barbers, who many had still shop at the time of the Municipality). The road is often transformed into art gallery outdoors, hosting young painters in search of affirmation.
