Piazza Flaminio is dedicated to the humanist and writer from Serravalle, Marcantonio Flaminio, and represents the beating heart of the historic center of Vittorio. It is flanked by buildings that symbolize the political and religious power of the ancient Municipality. The origins of the square date back to the Middle Ages, and its current layout is due to an expansion carried out in 1578 and a second expansion in 1830. Noteworthy is the flooring made of Istrian stone. Overlooking the square is the ancient Loggia of Serravalle, a jewel of Gothic-Venetian architecture, finely decorated with valuable frescoes attributed to Dario Da Treviso (15th century). Among the coats of arms stands out the Lion of San Marco, symbol of the Republic of Venice. The Civic Tower features two clock faces on its façade, among the oldest in the region. Attached to the Loggia, in its current museum function, are Casa Bernardini and Palazzo Torres.
Between the Loggia and the Austrian Arch stands Palazzo Todesco (15th-17th century) and Palazzo Cesana (1485). On the opposite side towards the ancient Cal Granda is Palazzo Piazzoni founded in 1542, which housed the old Mount of Piety. At the end of the square are the very tall antenna and the column of the town crier where edicts were read to the population. Along the riverbank is the house of Salomone, characterized by semi-buried arches, a testimony to the flood that struck Serravalle in 1521. The house overlooks the meschietti, a hydraulic work that, in addition to dividing the body of water, reduced the current to allow the work of the laundresses.
