Palazzo Vecchio has served as the seat of Florence's government since 1299, making it one of the longest continuously used town halls in Europe; the mayor's office still operates from part of the building today. Arnolfo di Cambio designed the fortress-like original, its 94 meter asymmetric tower placed off-center because it incorporates an earlier Ghibelline family tower the builders refused to demolish. Cosimo I de' Medici moved in during the 1540s and had Giorgio Vasari transform the interior into the Salone dei Cinquecento, a vast hall built for Florence's short-lived republican council and later covered in Vasari's own propagandistic ceiling paintings glorifying Medici rule. Beneath the palace, excavated Roman theatre remains connect the building to the city's ancient foundations, a layered history visitors can walk through on themed tours.
Palazzo Vecchio records Florence’s civic government, later Medici transformation and continuing municipal presence. It is part of the Historic Centre of Florence World Heritage property, not a separately inscribed site.
