Palazzo del Podestà

The Palazzo del Podestà forms the north side of Bologna’s Piazza Maggiore. The Comune acquired the site in 1201 for its own seat and the residence of the Podestà, the city’s chief magistrate. The palace is joined to the Torre dell’Arengo, whose bell summoned citizens to public assemblies, and its vaulted passage, the Voltone, is known for its unusual acoustic effect.

Why it matters

The palace was Bologna’s first seat of government under the Podestà, his judges and officers. The central block and chapel were complete by 1225; by 1245, magistrates could meet there, and the Podestà took up residence in 1253. The building therefore developed over several decades, before a major Renaissance refashioning transformed its Piazza Maggiore frontage.

What to notice

The Voltone del Podestà passes beneath the palace, where a particular acoustic effect allows people at opposite corners to hear one another. Above it, the Torre dell’Arengo marks the palace’s civic role. The Renaissance portico, completed in 1489, combines broad arches on massive piers with columns and a classical entablature. Its piers are densely carved with flowers, heraldic emblems and faces, some rendered as caricatures.

Context and history

The Arengo tower was completed in 1268. In 1472, during the rule of Giovanni II Bentivoglio, the palace underwent a major rebuilding; the portico was completed in 1489. The design follows an antique-inspired architectural language. Although an older tradition attributes it to Bramante, the Comune’s architectural account considers Aristotele Fioravanti more likely to have designed it, with the stonework executed by Marsilio Infrangipani.

In 1909, Alfonso Rubbiani proposed restoring a medieval appearance to the façade, including battlements and biforate windows. The proposal met opposition from citizens and intellectuals and was abandoned, leaving the Renaissance frontage in place.
