Palazzo Pubblico

Construction of the Palazzo Pubblico began in 1297 under the Republic of Siena's Council of Nine, the oligarchic body of merchants who governed the city at the height of its medieval power. The building grew in phases over the following decades: the central section was complete by around 1310, the side wings and battlemented upper floors added through the mid-fourteenth century, and the soaring Torre del Mangia completed in 1344. The great fresco commissions followed: Simone Martini's 'Maestà' in 1315, Lorenzetti's allegories between 1338 and 1340. The Nine fell from power in 1355, but their building survived them — successive Sienese governments continued to use the palazzo, and after Siena's absorption into the Grand Duchy of Tuscany in 1555, it retained its civic function. The UNESCO designation for Siena's Historic Centre, awarded in 1995, recognised the extraordinary preservation of the medieval cityscape, of which the Palazzo Pubblico and the Campo are the central element.

Getting there: The Palazzo Pubblico is on Piazza del Campo in the heart of Siena's historic centre. Siena is not on the main Italian rail network; the nearest mainline station is at Empoli (Florence–Siena branch) or Chiusi-Chianciano Terme. Frequent SENA/FlixBus coaches run from Florence's Santa Maria Novella station to Siena Piazza Gramsci (~1.5 hours); from Rome, coaches depart from Tiburtina (~2.5 hours). By car, park at Parcheggio Il Campo (outside the ZTL zone) and walk the short descent into the Campo.

Tickets: Museum entry costs approximately €15 for adults and €9 for children (Museo Civico only). The Torre del Mangia is a separate ticket (~€10) with its own timed entry slots — buy both at the palazzo ticket desk or online in advance. A GYG guided tour of the Museo Civico (t1446028, from approximately €15) provides expert context for the Lorenzetti and Martini frescoes; it is a new listing with no published reviews yet. The Torre del Mangia is not included in the GYG tour.

Practical tips: The Lorenzetti frescoes in the Sala della Pace are the reason most visitors come — allow extra time here and read the cycle from right (Good Government) to left (Bad Government) to follow the narrative logic. Photography is permitted without flash. The Campo itself is at its most dramatic early morning or early evening; the museum is generally less crowded on weekday mornings. Avoid the Palio dates (2 July and 16 August) unless attending the race — the Campo is blocked and the city is overwhelmed.

Combine with: [Monteriggioni](/castles/italy/monteriggioni) (~15 km north — a perfectly preserved circular medieval walled town on a hilltop, mentioned by Dante in the Inferno and visible from several Tuscan hilltops; one of the best-preserved examples of thirteenth-century military architecture in Italy) or [Brolio Castle](/castles/italy/brolio-castle) (~20 km southeast in the Chianti hills — the ancestral seat of the Ricasoli family, the producers of the original Chianti Classico recipe, with a wine estate open for tastings beneath the medieval walls).
