Florence won the war in 1555. Siena never forgave them. The tension between these two cities shaped banking, art, and the Tuscan identity for 700 years.
Plan my Italy trip →Florence and Siena are 68km apart by road and approximately 700 years apart in their relationship with each other. This is one of the oldest and nastiest city-state rivalries in Italian history, and it shaped everything from banking to art to the Tuscan dialect that became standard Italian. Understanding Florence vs Siena means understanding why one city has the Uffizi and the other has the Palio — and why both exist exactly as they are because of what the other city did to them.
Visit both — but if forced to choose one day for Siena, take it. Siena is what Florence would look like if the Medici had never happened: a perfectly preserved 13th-14th century city republic frozen at its peak moment of civic glory. The Piazza del Campo, the Gothic cathedral, the Palazzo Pubblico with its medieval frescoes — all extraordinary and with a fraction of Florence's crowds. Florence is larger, has world-class museums requiring advance booking, and is a full living Italian city. They complement each other and shouldn't be treated as alternatives.
The conflict between Florence and Siena was fundamentally about banking and control of the Via Francigena — the main pilgrim and merchant road running from France through Tuscany to Rome. In the 13th century, both cities were among the richest in Europe, competing fiercely for papal banking contracts. Florence was Guelf (supporting the papacy); Siena was Ghibelline (supporting the Holy Roman Emperor). The defining confrontation came on September 4, 1260, at the Battle of Montaperti, on the banks of the Arbia river east of Siena. A Sienese-Ghibelline army annihilated the Florentine forces. The casualty numbers in Florentine chronicles are probably exaggerated (10,000 dead), but the defeat was catastrophic and humiliating.
Dante, writing sixty years later, placed the Sienese commanders who fought at Montaperti in Hell — specifically in the frozen ninth circle, the deepest level for traitors. Dante was Florentine, recently exiled, and apparently still holding a grudge. The Black Death of 1348 killed 50-80% of Siena's population. Florence, also devastated, recovered faster due to its diversified banking networks (the Medici family was just beginning its rise). By 1555, after an 18-month siege that killed thousands, Cosimo I de' Medici incorporated Siena into the Grand Duchy of Tuscany. The Sienese have never forgotten. The Palio — the horse race run twice yearly in the Campo — is still partly an act of civic identity against historical absorption.
Massively underrated. Siena's painting school — Duccio di Buoninsegna, Simone Martini, the Lorenzetti brothers — was the direct precursor to the Renaissance and is almost never discussed adequately in standard art history courses. Duccio's Maestà in the Museo dell'Opera del Duomo is arguably the greatest work of pre-Renaissance Italian painting. The Palazzo Pubblico's Sala dei Nove contains Ambrogio Lorenzetti's "Allegory of Good and Bad Government" (1338-39) — the first secular fresco cycle in Western art, painted for the city council chamber showing a medieval city going about its daily life on one wall and suffering tyranny on the other. No religious subject. Just politics and its consequences. Florence's art is more famous and visited. Siena's is stranger, more intimate, and less understood by the crowds who pass through it.
The Palio is a bareback horse race run twice yearly (July 2 and August 16) in the Piazza del Campo — the city's shell-shaped central square. Ten of Siena's 17 contrade (medieval district guilds, each with an animal symbol, colors, and a church) compete, each with a jockey who can win, lose, or deliberately betray rivals mid-race for political reasons. The race lasts 90 seconds and the horse wins even without its rider. The preparation — political alliances, horse draws, trial runs, secret negotiations between contrade captains — takes weeks and involves genuine passions. Watching from inside the Campo is free if you arrive at dawn and stand in the center (no seats, no shade, very hot in August, very crowded). Grandstand seats cost €300-600 and sell out years in advance. Come on any non-Palio day, visit the Campo museum, and understand the ritual — the city will explain it to you willingly.
Siena makes an excellent day trip from Florence. The Tiemme bus from Florence (Via Santa Caterina da Siena terminal, near Santa Maria Novella) takes 1h15 for €8-9 round trip, runs frequently, and deposits you directly outside Siena's medieval walls. Alternatively, the train via Empoli takes 1h50 — the bus is faster and more direct. From Siena: the Campo, the Duomo (one of Italy's most elaborate Gothic facades with a floor of inlaid marble scenes), the Museo dell'Opera, and the Palazzo Pubblico can all be covered thoroughly in a focused 6-hour day. Alternatively, base yourself in Siena for 2 nights: it's cheaper than Florence, quieter, and a better base for southern Tuscany (Montalcino, Pienza, Montepulciano, Val d'Orcia) by rental car.
Siena's food scene is more intimately regional. Sienese specialties: panforte (dense spiced cake with candied fruit and nuts dating to the 13th century — the original was called "pane dei Saraceni" for its eastern spices), ricciarelli (chewy almond cookies made with marzipan base), pici al ragù (thick hand-rolled pasta with a slow-cooked meat sauce — more substantive than standard tagliatelle), and wild boar in every form from October onward. Florence owns bistecca alla Fiorentina (T-bone steak from Chianina cattle, grilled over oak charcoal, served rare — a proper one weighs 1kg), lampredotto sandwiches (tripe slow-braised in tomato with salsa verde, sold from street carts at Mercato Centrale), ribollita (thick vegetable and bread soup), and pappa al pomodoro. Both cities are surrounded by Chianti Classico vineyards — the wine improves everything.
Florence is far more crowded. The Uffizi and the Accademia (Michelangelo's David) require advance booking weeks or months ahead in spring and summer, and the centro storico in July feels like an outdoor version of an airport concourse. The Ponte Vecchio is permanently photographed. Siena receives significantly fewer tourists — partly because it's slightly less convenient, partly because most Tuscany itineraries put it in the optional column. This is Siena's great advantage: the Campo on a Tuesday afternoon in June has tourists but also Sienese university students eating lunch and old men playing cards. In Florence in the same week, almost everyone on the Piazza della Signoria is a visitor. Both are legitimate experiences. One is more peaceful and feels more like a real city.
You can — but you won't do either properly. The better strategy: one full day in Florence for the Uffizi or Accademia plus the Duomo and medieval center, then a second day to Siena (bus, 1h15 each way) with 6 hours on the ground. An alternative many experienced Tuscany travelers prefer: book 2 nights in Siena, use it as the base for a rented-car tour of Val d'Orcia and southern Tuscany, and make Florence a long day trip from Siena for the specific museums. This costs less overall and the daily quality of life (dinner, morning coffee, evening stroll) is higher in smaller Siena.
The Tiemme bus is the fastest and most practical option. Departs from the terminal at Via Santa Caterina da Siena (a 5-minute walk from Florence Santa Maria Novella station). Journey time: 1h15 direct (Corse rapide), arriving outside Siena's Piazza Gramsci near the north gates. Cost: approximately €8-9 round trip. Runs multiple times per day. By train: Florence SMN to Siena via Empoli takes 1h45-2h and requires a change — significantly less convenient than the bus. By car from Florence: 1h15 via the SS2 Via Cassia through the Chianti hills (the scenic option) or 45 min via the Raccordo Autostradale to Poggibonsi. By car you can stop at Greve in Chianti, Panzano, or Castellina in Chianti on the way — one of Tuscany's best drives.
Better, actually. The Campo is a naturally occurring shell-shaped piazza sloping gently toward the Palazzo Pubblico on the lower end — the nine segments of the paving (one for each member of the medieval Council of Nine that governed Siena) radiate outward from the palace like a fan. It's not a flat square but a slightly concave bowl, which means that sitting anywhere in the Campo you can see the full space without obstruction. There are no cars, no permanent market stalls, no fountains cluttering the center — just the paving, the Fonte Gaia fountain (a replica; the original Jacopo della Quercia sculptures are in the Museo Civico), and the Palazzo Pubblico with its slender Torre del Mangia. At dawn or dusk with few people: one of the genuinely beautiful urban spaces in Europe. In July at noon: very hot, very crowded. Timing matters.
Florence for volume and variety. The Mercato Centrale (covered market, Via dell'Ariento) has leather goods, clothing, food souvenirs. The leather workshops on and around the Oltrarno (particularly Via dei Serragli and Via Maggio) sell high-quality leather goods made locally — not manufactured in China with a Florentine label. Piazza Santo Spirito has a small antiques market on the second Sunday of each month. Siena's shopping is more specialized: Piazza del Campo and the streets around it have ceramics (local Sienese pottery with traditional geometric patterns), panforte, ricciarelli, and specialty foods. For books and prints: Siena's San Domenico area has a few excellent antiquarian dealers. For leather: Florence wins decisively.
Both cities are excellent in winter. Florence in December has modest Christmas markets (not as elaborate as German or Austrian ones), the Uffizi and Accademia are far less crowded (January and February are the emptiest months), and Florentine restaurants are at their best for the winter menu: ribollita, lampredotto, bistecca (the wood-fired steakhouses operate year-round). Siena in December: the Christmas presepe (nativity scene) displays in the churches are excellent, the Campo is quiet and beautiful, and the city has no off-season attitude — it functions the same year-round. Hotel prices in both cities drop 40-50% in January-February from summer peak. If you want the Uffizi with room to breathe in front of Botticelli: January morning is the time.
Yes, by rental car: Florence → Siena (1h15 via the Chianti route) → Pienza (45 min from Siena, the Val d'Orcia UNESCO village famous for Pecorino cheese and Renaissance urban planning) → Montalcino (30 min from Pienza, Brunello wine, medieval hilltop) → back to Florence via the A1 (1.5h). This is a full day, roughly 300km round trip, best done with an early start and a willingness to drive on winding provincial roads. Alternatively, the loop works as a 2-day rental with an overnight in Montalcino or Pienza. The Val d'Orcia in this loop is UNESCO listed for its landscape — the cypress-dotted hills, the wheat fields, the isolated farmhouses — and is one of the most photographed landscapes in Italy for good reason.
