Castello di San Fabiano, Monteroni d'Arbia
San Fabiano is a castle at Lucignano d’Arbia, in the Crete Senesi, the clay hills south of Siena.
The building is a fortified country house with a loggia and a walled garden, and the ground floor has been given over to events. In the grounds stand a pavilion built for large dinners and a twelve-metre swimming pool. Siena is 29 minutes north, and the castle runs a shuttle to the city gates.
Eleven rooms above the event floor make up the castle’s own bed-and-breakfast.
Castello di San Fabiano Wedding Venue
Sole use takes the ground floor, and the indoor capacity here is the thing that sets this venue apart.
The indoor rooms
Three hundred and twenty seated, which is the largest indoor figure of any venue in this region, across the castle’s connected ground-floor halls.
The Pavilion
A structure in the grounds seating 300, built as the wet-weather answer for a large wedding, with its own limit on music.
The Loggia Garden
The arcaded garden beside the castle, and the setting the estate recommends for a symbolic ceremony.
The pool
Twelve metres by six, open from May to October, reserved for guests staying at the castle.
Castello di San Fabiano Wedding Cost
A Castello di San Fabiano wedding starts from €150,000, and for optimal results we recommend budgeting €200,000 all-in for 150 to 320 guests.
Sole use with the rooms
Every figure includes the eleven castle rooms, breakfast for up to 22 guests, linen, towels, wifi and the pool:
- May to September: just under €5,000 for one midweek night, just under €9,000 for two, just over €12,000 for three; or just over €10,000 for two weekend nights and €13,000 for three
- April and October: just over €4,000 for one midweek night, just over €7,000 for two, €10,000 for three; or just under €5,000, just under €9,000 and just under €12,000 across a weekend
The event fee
Charged only above 30 guests, and banded: nothing up to 30, €600 to 80 guests, just over €1,000 to 160, and just under €2,000 above 160.
It covers the use of the indoor and outdoor spaces, the estate’s staff during the event, the cleaning before and after, the utilities, four hours of toilet attendance and two hours of parking assistance.
The extra hours
Each hour past midnight is €300, up to a limit of three in the morning.
What sits outside
All the catering, the flowers, the furniture, the lighting, the music and our fee. There is no kitchen operation here and the suppliers are appointed by us.

Two Thousand Euros for Three Hundred Guests
It is worth stopping on the event fee, because nothing else in Tuscany is priced like this.
A wedding of more than 160 guests pays an event fee just under €2,000. Add three weekend nights in high season with the eleven rooms at €13,000 and the entire venue line for a wedding of 300 people is about €15,000, which works out at roughly fifty euros a head.
The comparison is stark. A Chianti estate seating 130 charges more for the building alone. A hotel seating 120 charges more for the food minimum. San Fabiano seats 320 indoors and asks less than most venues ask to open a garden.
What the money does not buy is beds, and that is the whole trade. Twenty-two people sleep here and 320 can sit down, which is the narrowest ratio in our portfolio by a wide margin. The budget that other venues spend on hire gets spent in Siena instead.
The Pavilion Decides When the Party Ends
This is the detail we settle before a date is held, and the estate states it plainly.
Outdoor music runs to midnight. Indoor music runs to three in the morning, at €300 an hour past twelve. Music in the Pavilion is allowed until midnight, because of the way the Pavilion is soundproofed.
For a wedding of 300 that shapes the wet-weather plan. The Pavilion is the covered space that holds 300, so on a wet Saturday the party moves to the room where the music ends at midnight.
We plan around it in one of two ways. Either the guest list stays within the capacity of the castle’s own indoor halls, where three in the morning is available, or the budget carries a marquee as the wet-weather plan instead of the Pavilion. We always price the second option for a list above 200, because a marquee is booked months ahead rather than in the week of the wedding.
Accommodation at Castello di San Fabiano
Twenty-two guests in eleven rooms, including three suites and four deluxe rooms.
Breakfast comes with them, as do blankets, towels, courtesy sets, wifi and access to the pool between May and October. One condition applies in the busy months: from June to September, staying at the castle is compulsory for a weekend wedding, with a minimum stay attached.
Everyone else stays in Siena, 29 minutes away, where there is a 4-star hotel and a 3-star close by and a city’s worth of apartments beyond them. The castle runs its own shuttle to the city gates, which is unusual and genuinely useful for guests who want an afternoon in Siena on the Friday.
Castello di San Fabiano Location, Tuscany
The castle is on the Via di San Martino at Lucignano d’Arbia, in the comune of Monteroni d’Arbia, in the province of Siena.
Siena is 29 minutes and Monteroni d’Arbia five.
Getting guests there
Florence Peretola is an hour and 35 by road, Perugia an hour and 44, Bologna two hours and 22 and Pisa two hours and 23. Rome Fiumicino is three hours and 20.
Florence city centre is an hour and 31.
Half an hour from Siena with a shuttle to the gates is the practical answer to the bed count, and it means a guest list of any size can be housed in a real city rather than scattered across farmhouses.
Magic Day Insights
The cheapest large-wedding venue in Tuscany, a pavilion whose music ends at midnight, and 22 beds.
The event fee barely moves with the guest list.
The event fee tops out just under €2,000 above 160 guests and the indoor rooms seat 320. The marginal cost of another twenty guests here is catering and nothing else, which is true at almost no other venue in the region.
The Pavilion’s music stops at midnight.
The Pavilion holds 300 and its music stops at midnight. For a large wedding we price a marquee alongside it, so the wet-weather plan is chosen at the contract stage with both figures on the table.
Twenty-two beds inside, Siena for everyone else.
Twenty-two beds will cover the parents, the wedding party and the people who need to be in the building. The city is 29 minutes away with a shuttle already running, so the rest of the list is a hotel problem rather than a logistics problem.
April and October run about two thousand euros less than May.
Three nights in the shoulder months run about two thousand euros less and the Crete Senesi look their part in both. The pool opens in May, so that is the one thing an April wedding gives up.

Common Questions
How much does a Castello di San Fabiano wedding cost?
A Castello di San Fabiano wedding starts from €150,000, and for optimal results we recommend budgeting €200,000 all-in. The venue side is unusually cheap: €13,000 for three weekend nights in high season with the eleven castle rooms included, plus an event fee under €2,000 for a wedding of more than 160 guests. Catering, flowers, music and planning are where the budget goes.
How many guests can attend a Castello di San Fabiano wedding?
Three hundred and twenty seated indoors, which is the largest indoor capacity we work with in Tuscany, and the Pavilion in the grounds takes 300 as a wet-weather alternative. One of the smaller rooms seats 80. Only 22 of those guests can sleep at the castle, so the accommodation rather than the capacity is what shapes the plan.
Can we marry legally at Castello di San Fabiano?
The legal civil ceremony is celebrated at a town hall: Monteroni d'Arbia is five minutes away, Buonconvento fifteen and Siena twenty. At the castle the ceremony is symbolic, and the estate recommends the Loggia Garden. We arrange the appointment, the paperwork and the interpreter, and the five-minute option means the convoy is short.
What is the music curfew at Castello di San Fabiano?
Outdoor music runs until midnight and indoor music until three in the morning, with each hour after midnight charged at €300. The one exception matters: the estate limits music in the Pavilion to midnight because of its soundproofing, so if rain moves the wedding into the Pavilion the curfew moves with it, and we plan the wet-weather cover around that.
How many people can sleep at Castello di San Fabiano?
Twenty-two, in eleven rooms including three suites and four deluxe rooms, with breakfast and a twelve-metre swimming pool reserved for resident guests. From June to September staying at the castle is compulsory for a weekend wedding. Everyone else stays in Siena, half an hour away, and the castle runs a shuttle to the city gates.
Which airport do guests fly into for Castello di San Fabiano?
Florence Peretola, an hour and 35 minutes by road, with Siena only 29 minutes away. Perugia is an hour and 44, Bologna two hours and 22 and Pisa two hours and 23. Rome Fiumicino is three hours and 20 for long-haul arrivals.
When is the best time of year for a Castello di San Fabiano wedding?
May or September. April and October are about two thousand euros cheaper across three nights and the pool opens in May, so the shoulder months are genuinely worth pricing. The Crete Senesi are green in spring and bare gold by late summer, and both photograph well.
