San Quirico d'Orcia: what to see and why it's worth the detour
San Quirico d’Orcia is one of the places in the Val d’Orcia that is most worth visiting and least often visited. It does not have the architectural drama of Pienza or the wine prestige of Montalcino. It does not have a single famous view that appears in travel magazines. What it has is a Romanesque church with three of the finest carved portals in Tuscany, a formal Renaissance garden that is free to enter, and a quality of unhurried life that the larger towns have largely traded away for tourist infrastructure.
From Barberino Val d’Elsa the distance is about 75 km and the drive takes roughly 65 minutes on the SR2 south through Siena and then along the SR2 toward the Val d’Orcia. San Quirico sits at the intersection of this road and the SP146 — the famous Val d’Orcia scenic road — making it a natural and logical first stop on any excursion into this part of Tuscany.
San Quirico d’Orcia what to see
San Quirico d’Orcia was a significant staging post on the Via Francigena, the medieval pilgrimage route that connected Canterbury in England to Rome. Pilgrims, merchants, and papal envoys passed through here for centuries, and the town’s monuments — particularly the Collegiate Church — reflect the wealth and ecclesiastical investment that this traffic generated.
The historic centre is compact. You can walk from the main northern gate to the southern edge of the town in about ten minutes. The main street runs straight through, lined with modest medieval buildings, a few shops selling local food products, and a small number of bars and restaurants that serve locals more than tourists.
Begin the visit at the main gate on the northern side of town. Walk south along the corso and you will reach the Collegiate Church in about three minutes. After the church, the Horti Leonini garden is a further two minutes on foot. The Palazzo Chigi Zondadari is visible from the central piazza.
Allow two to three hours for the whole town. Combine it with Bagno Vignoni, 5 km south, on the same half-day.
The Collegiate Church and Horti Leonini
The Collegiate Church of SS. Quirico e Giulitta is the reason most architecturally attentive visitors come to San Quirico. The building dates from the 12th century and was extended and modified over the following two hundred years. What makes it exceptional is not the overall building but the three portal entrances, each carved at a different period and in a different stylistic register.
The main portal, on the west facade, dates from the early 12th century. It features twisted columns resting on lions — a motif common in northern Italian Romanesque but rendered here with unusual refinement. The capitals and archivolt decoration are intricate, with carved animals, interlocking plant forms, and human figures worked into the stone with a precision that has survived eight centuries of weather and handling.
The Hoysala portal on the south side was created in the late 12th century and shows the influence of craftsmen who may have come from further east, possibly from the Apulia or the Levant. Its decorative vocabulary is different from the main portal: more geometric, more densely packed.
The third portal, added in the 14th century, is simpler in form but structurally important to understanding how the building developed over time.
Inside the church, the space is austere and cool. A polyptych by Sano di Pietro hangs in the nave. The stone floor, the carved wooden choir, and the quality of silence all reward slow attention. There is no entry fee.
The Horti Leonini is a formal Italian garden laid out in 1580 on the southern edge of the historic centre. It was commissioned as a public garden — an unusual act of civic provision in 16th-century Tuscany — and designed around geometric beds of clipped holm oak and box. A statue of Cosimo III de’ Medici stands at the centre. Entry is free.
The garden provides shade and seating, and the views from the upper terrace look south over the countryside. In summer it offers genuine relief from the heat of the stone streets. In autumn, when the surrounding landscape has turned from green to ochre and the hedges hold their dark colour against the faded hills, the garden is quietly beautiful.
Bagno Vignoni: the historic baths
Bagno Vignoni is 5 km south of San Quirico on the road toward Abbadia San Salvatore. The drive takes 8 minutes.
The thermal spring at Bagno Vignoni has been in use since Etruscan times. The Romans constructed baths here. In the medieval period the hot water became an established stop on the Via Francigena: Lorenzo de’ Medici is documented as having visited, and Pope Pius II — who also shaped Pienza — took the waters here for his gout.
The central piazza of the village is entirely occupied by the vasca grande, the large thermal basin built during the Renaissance and measuring roughly 45 by 29 metres. The water is no longer open for public bathing in the main pool — a preservation order in the 1990s ended that — but it remains filled with steaming water at around 52 degrees Celsius. The effect of walking into a village piazza and finding a large pool of thermal water instead of paving stones is genuinely arresting.
Below the village, the thermal water flows into the gorge of the Orcia river. A walking path descends from the village to the old Mulino (mill) and the natural hot springs that emerge at the base of the cliff. The path takes 20 to 30 minutes and is accessible to anyone who can manage uneven stone steps. At the bottom, the contrast between the warm spring water and the cool river below is both visible and palpable.
Several hotels in Bagno Vignoni offer thermal pool access to day visitors. Terme Posta Marcucci and Adler Thermae both have outdoor pools fed by the thermal spring at temperatures around 38 to 40 degrees Celsius. Day access costs typically between 20 and 35 euros per person. Booking ahead for day passes in peak season is advisable.
Palazzo Chigi Zondadari
The Palazzo Chigi Zondadari occupies the east side of San Quirico’s central Piazza della Libertà, directly across from the Collegiate Church. It was built in the 18th century as a summer residence for the noble Chigi family, who were prominent in Sienese and papal politics over several centuries.
The building is not always open to visitors. The exterior facade — an elegant 18th-century composition in local stone — is the most visible element. The ground floor loggia and courtyard can sometimes be seen from the piazza. Temporary exhibitions are occasionally held inside.
The palazzo’s most important contribution to the town is urban rather than architectural: it gives the central piazza a proper public character. With the church on one side and the palace on the other, the piazza achieves the kind of formal balance that the best small Italian squares are built around. The space between the two buildings is not large, but it is well-proportioned and comfortable to inhabit.
How to get there from Barberino Val d’Elsa
Take the SR2 Cassia south from Barberino toward Siena. Follow the Siena raccordo ring road and continue south on the SR2 toward Buonconvento. After Buonconvento continue south on the SR2 following signs for San Quirico d’Orcia.
Total distance: approximately 75 km. Drive time: approximately 65 minutes. Traffic through the Siena ring road can add 10 to 15 minutes during morning or evening peak hours.
Parking is available outside the historic walls, primarily on the northern side. The car parks here are free and within a short walk of the main gate.
From San Quirico you can reach Bagno Vignoni in 8 minutes (5 km), Montalcino in 30 minutes (26 km west), and Pienza in 25 minutes (25 km east). The town is a natural hub for a Val d’Orcia day that takes in multiple sites.
Where to stay
Sogno d’Oro in Barberino Val d’Elsa is 65 minutes from San Quirico d’Orcia. The guesthouse is a comfortable base for a Val d’Orcia day: leave in the morning, move between San Quirico, Bagno Vignoni, and one or two other towns through the day, and return in the evening with the Val d’Elsa landscape waiting as the quiet counterpart to the more dramatic scenery of the south.
