Best Things to Do in Siena (2026 Guide)

The Torre del Mangia rises 102 meters above Siena’s Piazza del Campo, its slender brick shaft capped with a white stone crown that makes it visible from the surrounding Sienese hills on clear days. Built between 1338 and 1348, it was among the tallest secular towers in medieval Italy, a deliberate statement that civic authority could reach as high as the bell towers of the church.

The tower is named after a legendary bell-ringer, Giovanni di Balduccio, known as Mangiaguadagni or “earnings eater” for his prodigal spending — a nickname that passed to the tower and the mechanical bell-striker that eventually replaced him. Climbing the tower’s 400 steps brings visitors to the top of the Campo’s skyline, with views across the piazza’s herringbone brick below and over the rooftops of the medieval city toward the Sienese countryside beyond.

Tickets for the climb are sold at the Palazzo Pubblico adjacent to the tower base and include access via a narrow internal staircase. The climb takes around twenty minutes at a moderate pace and requires reasonable physical fitness; the staircase narrows considerably toward the top. Visitor numbers are limited at any one time, and booking in advance during summer months is advisable. The tower is closed in poor weather.

In the context of Siena’s medieval fabric, the Mangia Tower functions as the counterpoint to the cathedral’s campanile, each marking a different kind of power within the city. The towers’ co-existence illustrates the negotiated balance between religious and secular authority that characterized Italian city-states at their height, with both institutions competing to demonstrate, in stone and height, whose reach extended further.

Painted walls and illuminated manuscripts transform a small library inside Siena Cathedral into one of the most vividly decorated rooms in Italy. The Piccolomini Library, built at the end of the fifteenth century to house the books and celebrate the memory of Pope Pius II, is lined with a cycle of frescoes by the Umbrian painter Pinturicchio depicting scenes from the pope’s life and career. The colors — deep blues, warm ochres, and bright greens — have retained an intensity unusual for work of this period.

Ten large fresco panels cover the walls from floor to ceiling, narrating episodes from the life of Aeneas Silvius Piccolomini, who became Pope Pius II in 1458. The scenes move from his early career as a humanist diplomat through his election and reign, rendered with the precise attention to costume, architecture, and landscape detail characteristic of Pinturicchio’s best work. At the center of the room stands a famous ancient Roman sculpture of the Three Graces, which the Piccolomini family acquired and kept here for centuries.

The Piccolomini Library is entered from the left nave of Siena Cathedral and requires a separate ticket from the cathedral itself, though combination tickets are available. It is a small space and can feel crowded when tour groups are present; arriving early in the morning or in the late afternoon improves the experience considerably. Allow twenty to thirty minutes inside; the frescoes reward slow looking. The library is generally open year-round except during major liturgical celebrations.

Within Siena’s extraordinary concentration of medieval and Renaissance art, the Piccolomini Library stands apart for the completeness of its decorative program and its excellent state of preservation. It offers a rare opportunity to experience a fifteenth-century interior as something close to its original appearance, undimmed by restoration or the accumulation of later additions.

For five centuries, the building across the piazza from Siena’s cathedral served as a hospital, receiving pilgrims on the Via Francigena, sheltering orphans, and housing the sick in wards decorated with frescoes commissioned to both comfort and edify. Santa Maria della Scala is no longer a hospital but has become one of Italy’s most ambitious museum complexes — a layered space where medieval infrastructure and great art coexist in a building of exceptional historical depth.

The most celebrated space is the Pellegrinaio, the former pilgrims’ ward, whose walls carry a narrative fresco cycle painted in the 15th century depicting the hospital’s history and charitable works with documentary specificity. Other areas include the Oratorio di Santa Caterina della Notte, a vaulted underground chapel used by a confraternity, and a series of archaeological spaces revealing Roman and medieval remains beneath the building. The complex also houses part of the Museo Civico’s collections and the Museo Archeologico Nazionale di Siena, giving a single admission ticket considerable scope.

The scale of the complex means a full visit can easily last three hours or more, so arriving early and allowing the whole morning is wise. The underground sections are cool even in summer. Unlike the Cathedral Museum directly across the piazza, Santa Maria della Scala is rarely rushed, and its size means that even on busy days there are quieter corners. Combination tickets with other Siena museums offer good value.

The position of Santa Maria della Scala — opposite the cathedral on one of the most architecturally charged public spaces in Italy — reflects the medieval understanding that spiritual and bodily care belonged together. The building’s conversion from functioning hospital to cultural complex preserved its fabric rather than replacing it, making a visit here an encounter with Sienese civic life across nearly eight hundred years.

On the ground floor of the Palazzo Pubblico — the medieval civic palace that forms the dominant structure on Il Campo, Siena’s extraordinary shell-shaped piazza — the Siena Civic Museum holds a collection that is inseparable from the building it occupies. The rooms were never simply storage for art; they were the working chambers of the Sienese republic, and the paintings on their walls functioned as political statements addressed to the officials who governed from them.

The most celebrated works in the museum are the frescoes painted by Ambrogio Lorenzetti in the 1330s in the Sala della Pace, depicting the Allegory of Good and Bad Government. These are among the most ambitious secular paintings to survive from medieval Europe — panoramic urban and rural scenes that use allegory to make an explicit argument about the consequences of just and unjust rule. The painted city in the Good Government fresco is recognizably Sienese, with details of architecture, trade, and daily life that make it an invaluable document of medieval urban culture as well as a political masterpiece.

The museum also contains Simone Martini’s Maestà, one of the defining works of the Sienese school, in the Sala del Mappamondo. Admission is separate from the piazza but included in combined Siena museum tickets. The museum is best visited in the morning when the rooms are quieter and the fresco colors are at their most legible in natural light.

The Civic Museum’s significance lies in the almost unique coincidence of original function and surviving art — the frescoes were painted for these specific rooms, to be seen by the specific people who used them. That continuity between artwork and institutional context is extraordinarily rare in Italian civic culture and gives the visit a clarity of meaning that most museum collections cannot achieve.

The Basilica of San Domenico in Bologna anchors the southern edge of the historic centre with a gravity that belies its relatively plain exterior. Founded in the thirteenth century as the mother church of the Dominican order — Saint Dominic himself died in Bologna in 1221 and is buried here — it has accumulated over eight centuries a collection of art and funerary monuments that makes it one of the most richly layered religious buildings in northern Italy.

The tomb of Saint Dominic, the Arca di San Domenico, is the basilica’s central object of veneration and artistic interest. The sarcophagus was begun by Nicola Pisano in the thirteenth century and completed over subsequent decades by a succession of sculptors, including the young Michelangelo, who carved three of the small figures that complete the upper portion of the monument. The basilica also contains paintings by Guido Reni and a series of wooden choir stalls with intarsia decoration. A small museum adjacent to the church displays additional works from the Dominican community’s collection, including illuminated manuscripts and devotional objects.

The basilica is open daily and admission to the main church is free, with a modest charge for the museum. Morning visits are quieter and offer better light for examining the details of the Arca. The surrounding Piazza San Domenico, with its column monuments, provides a pleasant outdoor space before or after the visit. The basilica is within comfortable walking distance of the city’s main portico-lined streets and the Piazza Maggiore.

San Domenico distinguishes itself among Bologna’s many churches through the specific weight of its founding history and the remarkable density of artistic patronage it attracted across several centuries, concentrated most memorably in a single funerary monument of exceptional quality.

The Fonte Gaia occupies the highest point of the Piazza del Campo in Siena, its white marble basin set against the curve of the medieval buildings that enclose the square. The fountain’s name — the Joyful Fountain — reflects the celebration that greeted the completion of the aqueduct that first brought fresh water to this point in 1346, an engineering achievement that transformed daily life in the hilltop city. The current sculptural decoration is a nineteenth-century reproduction; the original reliefs by Jacopo della Quercia, carved in the early fifteenth century, are preserved in the Museo Civico inside the Palazzo Pubblico nearby.

The fountain serves as the upper anchor of the Campo, the point from which the square’s distinctive nine-segment pavement descends toward the Palazzo Pubblico and its tower. Della Quercia’s original programme included figures of the Virtues, the Madonna and Child, and scenes from the early history of Siena, all executed in a style that bridges the Gothic and the emerging Renaissance vocabulary of the early Quattrocento. The reproductions in the Campo convey the general composition while the originals in the museum allow closer examination of the carving quality and the condition of the surviving marble.

The Piazza del Campo is accessible at all hours and the fountain is most pleasantly seen in the morning before the square fills with visitors. In summer, the Campo becomes extremely busy by mid-morning; early risers find the space almost to themselves. The fountain is a natural starting point for any exploration of the square and the buildings surrounding it.

The Fonte Gaia connects Siena’s medieval infrastructure to its civic artistic ambition, marking the spot where the solution to a practical problem of water supply became the occasion for one of the most significant sculptural commissions of the early fifteenth century in Tuscany.

Below the Siena Cathedral, reached by a staircase from the north side of the Piazza del Duomo, the Baptistery of San Giovanni occupies a lower level of the cathedral complex in a vaulted Gothic space whose walls and ceiling were frescoed in the fifteenth century by artists from the Sienese and Florentine traditions. The room is relatively small and often quiet even when the cathedral above is busy, giving it an intimacy that contrasts with the scale of its neighbors.

The centerpiece of the Baptistery is its marble font, one of the most important examples of early Renaissance sculpture in Italy. Commissioned in the 1420s and 1430s, its gilded bronze relief panels were assigned to different sculptors, including Jacopo della Quercia, Lorenzo Ghiberti, and Donatello. Donatello’s panels — the Feast of Herod and the figure of Faith — are among his earliest dated works in relief, and their spatial depth and emotional intensity mark a clear break from the Gothic conventions still present in the other panels. The font is small enough that each work can be examined closely without difficulty.

The Baptistery is included in the combined cathedral ticket and can be visited at any point during that ticket’s validity. Early afternoon is typically the quietest period. The space requires only thirty to forty-five minutes, but the quality of the sculpture rewards slow attention rather than a quick pass.

Siena’s Baptistery occupies an unusual position in the history of Renaissance art — it contains works by artists who were simultaneously developing the same visual language in Florence, making it a reminder that the early Renaissance was not a single-city phenomenon. In a city that otherwise maintained a distinct Gothic identity well into the fifteenth century, the font marks a significant and concentrated departure.

Twice each summer, the shell-shaped Piazza del Campo in Siena transforms into a dirt track for a horse race that lasts barely ninety seconds but generates months of preparation, fierce neighborhood rivalry, and an intensity of collective emotion unlike almost any other public event in Europe. The Palio — run on July 2 and August 16 in honor of the Virgin Mary — is not a tourist spectacle staged for visitors but a living expression of Sienese identity that has continued in essentially its current form since the 17th century.

Ten of Siena’s seventeen contrade, or city wards, compete in each race, their jockeys riding bareback on horses assigned by lot. The days preceding the race are filled with trial heats, ceremonial processions in medieval costume, and the intense political maneuvering of alliances and betrayals between contrade. The historic pageant that precedes the race itself, with flag throwers and drummers in period dress, is a performance of civic memory as much as spectacle. Winning — and the celebrations that follow — can define a contrada’s collective spirit for years.

Viewing from inside the piazza is free but requires arriving many hours early to claim standing space in the center, which becomes extremely crowded and offers no shade or facilities. Grandstand tickets along the track perimeter must be booked well in advance and carry significant cost. Hotels in Siena fill months ahead for both race dates.

The Palio cannot be fully understood in a single visit. Its meaning is embedded in centuries of neighborhood loyalty and civic competition that make Siena one of the most distinctively organized medieval cities surviving in Italy.

Long before the Uffizi assembled its encyclopedic collection in Florence, Siena was producing painters who transformed European art. The National Art Gallery of Siena, housed in the medieval Palazzo Buonsignori on Via San Pietro, holds the most concentrated collection of Sienese painting in existence — a sequence of works that charts the development of a distinct visual tradition from the 13th century through the Renaissance and beyond.

The collection is arranged chronologically across several floors, allowing visitors to follow the arc from the gold-ground devotional panels of the Duecento through the refined elegance of artists such as Duccio di Buoninsegna, Simone Martini, and the Lorenzetti brothers. Unlike Florentine painting of the same period, Sienese work maintained a lyrical, decorative quality and a particular intensity in the rendering of sacred figures that persisted well into the 15th century. Works from lesser-known masters fill in the picture, making the gallery essential for anyone interested in medieval and early Renaissance Italian art beyond the standard canon.

The gallery is rarely crowded compared to the major Tuscan art museums, which allows unhurried time in front of individual works. A visit of two hours covers the main collection comfortably; art historians and specialists may want considerably longer. Afternoon light enters some of the upper rooms well, though the building’s medieval fabric means lighting conditions vary. The museum is closed on certain public holidays, so checking hours before visiting is advisable.

Set in Siena’s Terzo di San Martino neighbourhood, the gallery stands a short walk from the Piazza del Campo and the Cathedral complex. Its proximity to Santa Maria della Scala and the Cathedral Museum means that a full day in Siena can be structured around these three institutions, giving a comprehensive view of the city’s extraordinary medieval cultural output.

Between the cathedral and the Baptistery on Siena’s Piazza del Duomo, a door leads into a complex that was for centuries the administrative and artistic heart of the cathedral’s operations. The Siena Cathedral Museum — the Museo dell’Opera del Duomo — houses works removed from the cathedral for preservation, the most celebrated of which is Duccio di Buoninsegna’s Maestà, one of the defining monuments of European medieval painting, displayed here in a dedicated room that allows examination of both its front and reverse sides.

The Maestà, completed in 1311, was carried through the streets of Siena in a civic procession when it was delivered to the cathedral — a measure of the work’s importance to the city. On its front, the enthroned Virgin is surrounded by a hierarchy of saints and angels rendered in gold and colour of extraordinary quality. The reverse carries narrative scenes from the Passion that represent some of the earliest examples of convincing spatial organisation in Italian painting. The museum also holds sculptures by Giovanni Pisano removed from the cathedral facade, where replicas now stand, and a collection of embroidered vestments and liturgical objects of considerable quality.

The museum’s rooftop terrace, accessed via a narrow staircase, provides one of the finest views of Siena’s Campo and skyline — a perspective that many visitors consider among the best in the city. The terrace visit is included in the standard ticket. Mornings tend to be less crowded than afternoons. Allow 90 minutes to two hours for the full complex.

The Cathedral Museum sits within the Siena OPA pass system, which combines entry to the cathedral, the museum, the Baptistery, and other connected sites into a single ticket offering considerable value. This makes it logical to plan a full day around the cathedral complex, treating the museum as the essential complement to the cathedral itself rather than a secondary attraction.
