It is divided in two borghi (ancient quarters): Borgo Piazza (Square's Quarter), developed in the 15th through 18th centuries, and Borgo Vecchio (Old Quarter), dating from the Middle Ages. Rich in mediaeval, Renaissance and Baroque buildings, it is characterized by the ancient portici (arcades), built on both sides of via Roma (the main street of the old town) but also along other streets, such as via Cavour, via Garibaldi, via Barotti, via Muratori. On the Eastern side, the old town is delimited by viale Mellano, a pedestrian promenade with views of Langhe; while on the Western side, along via Martiri dell'Indipendenza, viale Sacerdote and viale Bianco, there is a view of South-western Alps, whose apex is Monviso.
