Siena sits in Tuscany, 37 miles (60 km) from Florence, and it suits travelers who want a medieval center they can cross on foot, with a famous shell-shaped square, a cathedral complex and a calendar of summer and Christmas events. Florence makes an easy starting point, with buses and trains running between the two cities through the day.
The historic center is closed to traffic, so a rental car stays outside it. The railway station is about 0.6 miles (1 km) from the old town, and the Museo Civico is about 1.2 miles (2 km) from the station. Plan on walking or taking a local bus for the last stretch.

Where is Siena and what is it like?
Siena is in Tuscany, 37 miles (60 km) from Florence.
The heart of the city is Piazza del Campo, a square with a shell shape that the tourist board calls unique in the world. Piazza San Domenico is a wide medieval terrace with a view over the Cathedral, the valley of Fontebranda and the Tuscan countryside. The historic center can be walked in reasonable times, so the pace here is a walking one.
The historic center of Siena was recognized as a UNESCO World Heritage site in 1995. Inside the Palazzo Pubblico, Ambrogio Lorenzetti painted the Allegory of Good Government between 1338 and 1339. The Santa Maria della Scala complex was a hospital for pilgrims, lone women, abandoned children and the poor from the second half of the 12th century, and it stayed a hospital until 1996.
What is there to do in Siena?
Piazza del Campo and Piazza San Domenico
Piazza del Campo is the heart of Siena. The shell shape makes it a place to sit and look before going anywhere else. It also hosts events: Chigiana concerts on July 18 and 19, other events from July 21 to 23, and a concert by Francesco Gabbani on December 31, 2026.
Both squares sit inside the historic center, which is closed to traffic. Arrive on foot or by bus and leave the car outside. On event dates, expect the square to be in use.
Siena Cathedral complex
The Siena Cathedral is one of the most significant examples of Italian Romanesque-Gothic architecture. The complex is more than the church. It includes the Cattedrale, the Libreria Piccolomini, the Museo dell’Opera, the Panorama dal Facciatone, the Cripta, the Battistero and the Porta del Cielo.
With seven parts, the complex takes real time. Choose what interests you most before you go in, because the list covers art, a library, a crypt and a panoramic viewpoint.
Santa Maria della Scala
The Santa Maria della Scala is a museum complex at Piazza Duomo 1.
It offers guided tours for groups and for individuals, and activities for children and families.
Museo Civico, the Pinacoteca and the Bottini
Siena’s museums include civic, diocesan, university and foundation-owned museums. The Pinacoteca Nazionale is at Via di San Pietro 29. The Oratorio di San Bernardino e Museo Diocesano di Arte Sacra is at Piazza S. Francesco 9. The Museo Civico offers a free audioguide app in Italian, English, French, German and Italian sign language.
Download the audioguide app before you go.
The Bottini of Siena are underground galleries hand-carved into the tufa rock starting in the Middle Ages. They suit travelers who like a less obvious sight after the main squares.
Markets, food and festivals
Gusto Lovers fills piazza del Mercato on May 24 with dishes by chefs. Thirty local restaurants take part in Saranno Famosi nel Vino, which extends the fair outside the Fortezza. In summer, Sboccia l’Estate starts June 21 between Teatro dei Rinnovati and Cortile del Podestà.
Winter brings Mercato nel Campo, a fixed appointment before Christmas, held December 4 to 8, 2026. The Christmas markets run from November 29, 2026 to January 6, 2027.
Art and history lovers should start with the cathedral complex and the Museo Civico. Food lovers should plan around May 24 or the Christmas markets.
Where to stay in Siena
The simplest base is the historic center, where hotels and b&bs are often housed in ancient historic buildings. You can walk to Piazza del Campo and the cathedral and skip the daily trip from outside.
Just beyond the city gates, or in farmhouses and rural houses in the Sienese countryside, there are quieter options. A car is useful for those, since the historic center is closed to traffic.
On a budget, the municipal hostel Casa delle Balie is in the heart of the historic center, near the Duomo and Piazza del Campo. It has 25 beds: two dormitories of 8 beds each and three rooms with three beds. For the July and August events and the Christmas weeks, book early.

When should you go to Siena?
Late spring and early fall suit walking days best. May reaches a high of 73°F (23°C) and September 77°F (25°C), with mild nights and lighter heat than midsummer.
July and August bring highs near 87°F (31°C) and the fewest rainy days of the year, about 3 to 4. That is good for outdoor events, but the afternoons are hot for climbing streets. In summer you can catch the Chigiana concerts on July 18 and 19 and events in Piazza del Campo from July 21 to 23.
January highs reach only 50°F (10°C). Christmas visitors get the Siena Incanta programme, which runs from November 28, 2026 to January 31, 2027, and the markets, so pack for rain and cold.
