It was called "Piazza del Duomo" but it was renamed "Piazza Cavour" after the First World War. It is the oldest city square, the heart of the village built nearby the Castle during the fourteenth century. Formerly known as platea nobilum — Square of the Nobles — it hosted places of civil and ecclesiastical power and the first noble residences outside the Borgo Castello ("Castello Village): the Duomo built on the church dedicated to Saints Ilario and Taziano mentioned in the early decades of the fourteenth century, the gothic house of Simon Volker of the Ungrispach (1441) and the palace of the provincial States (1545), now the Questura headquarters (central police station), where the administrative and judicial functions were exercised.
