The western side, the shortest one, features the Baroque Palazzo Maffei, decorated by statues of Greek gods.
The north-western side occupies the site of the ancient Roman Capitol Hill, which looked towards the forum.
On the southern side is the crenellated Casa dei Mercanti ("House of the Merchants", also known as Domus Mercatorum), now the seat of the Banca Popolare di Verona.
The square's most ancient monument is the fountain (built in 1368 by Cansignorio della Scala), surmounted by a statue called Madonna Verona, which is however a Roman sculpture dating to 380 AD.
Also historical is the capitello, dating to the 13th century, during which it was used for several ceremonies, including the oath of investment of the city's medieval podestà and pretors.
