The Focheraccia bonfire, every 18 March

Fiorentino, three castles, an aviator and a bonfire

Fiorentino is the southern San Marino castello that calls itself the land of three castles. It has 2,593 residents on 30 June 2026 and 6.56 km². At Pennarossa you can see foundations, the keep and a cistern cut into the rock, and in 1913 the aviator Gianni Widmer landed here after the first flight over the country.

  • Fiorentino is a southern San Marino castello with 2,593 residents and 6.56 km².
  • It calls itself the land of three castles; Pennarossa still has its keep and a rock-cut cistern.
  • In 1913 Gianni Widmer landed here after the first flight over San Marino.
  • Its best-known festival is the Focheraccia bonfire on 18 March.

Of the lower castelli, Fiorentino is the one I'd pick for proper ruins. I'd head up to Pennarossa, cleared in the 1960s and still with its keep, and if I could make the dates work I'd come on 18 March for the bonfire.

Before you go

What I would keep in mind

  1. 01 Most beautiful

    The ruins of Pennarossa

    Cleared and made safe from the early 1960s, they show the foundations, the keep, the wall walks and a cistern carved into the rock. Nothing is left of the third castle, Torricella.

  2. 02 Worth the splurge

    Come on 18 March, Focheraccia night

    It's the fire festival in honour of St Joseph, and the council itself says it's better known than the patron's feast. The castello festival, for St Bartholomew, is on the last Sunday of July.

  3. 03 My tip

    The Wednesday market

    Every Wednesday morning, 07:00 to 13:00, there's a fruit, veg and fish market beside the Due Archi restaurant. The council suggests parking behind it and arriving via the San Giovanni turn.

Fiorentino bills itself as the land of three castles, and it’s one of the few lower castelli where genuine medieval stonework is still visible. It also has two stories I’m very fond of, one about an aviator who landed here in 1913 and one about a bonfire that every 18 March outshines the patron saint’s own feast.

Three castles, two half standing

The castello council names them one by one. The ruins of Castellaccio and Pennarossa can still be seen. Pennarossa was cleared and made safe from the early 1960s and now shows its foundations and keep, plus the wall walks and a cistern hewn from the rock. Of the third, Torricella, there’s no trace. If I could choose only one spot in Fiorentino, I’d walk up to Pennarossa.

Wikipedia fills in the history. Fiorentino is first recorded in 1069, among properties given to St Peter Damian, and from the 13th to the 15th century it belonged to the Counts of Carpegna, so much so that one branch of the family took its name. It passed to the Malatesta in 1440, and in 1463 Federico da Montefeltro and the Sammarinese took it, a gain Pope Pius II confirmed in a bull of 27 June that year. The defences were then dismantled. What came next is in the history of San Marino.

The aviator of Monte Carlo

In 1913 the Trieste-born aviator Gianni Widmer made the first flight over San Marino. According to the council, his 50-horsepower Blériot climbed to 1,600 metres and landed on the plateau after eleven minutes. Wikipedia gives the date as 16 April and places the landing on the plateau of Monte Carlo, at 508 metres. A memorial stone by the sculptor Carlo Reffi, with an inscription by Pietro Franciosi, marks the spot, and the same encyclopaedia says it was only the second monument in the world raised to an aviator. It’s one of my favourite small facts about the country.

Garibaldi and the Vascone

In the garden of a farmhouse not far from the centre you can still find the Vascone. The council says Garibaldi and his men would have stopped here on the night of 30 July 1849 to drink and rest on their march towards Venice. It tells it in the conditional, and so shall I. Up in the capital, the same episode ends at the church of San Quirino, where he disbanded his legion the next day.

There’s older archaeology too. Tombs from the Roman Republican period were found in 1910, and the State Museum keeps a vase and several fragments from that find.

The Focheraccia and the market

The castello festival falls on the last Sunday of July, for St Bartholomew, patron of the village’s modern church. But the council says plainly that the fire festival, the Focheraccia on 18 March in honour of St Joseph, is even better known. In 2024, per the official calendar, the castello festival ran from 26 to 28 July. Since the 2026 list isn’t out, I’d check dates with the council. Everything else in the year is in San Marino’s events.

If you’re here on a Wednesday, there’s a fruit, veg and fish market in the morning, 07:00 to 13:00, next to the Due Archi restaurant. The council suggests using the car park behind the restaurant and arriving via the turn for San Giovanni sotto le Penne.

Getting there

Two AASS services reach it from the capital. Line 1 starts at car park P9, crosses Murata and stops here on the way to Chiesanuova, while the circular lines 3D and 3S from P2 link it with Faetano and Montegiardino. All run on weekdays; other times, book the SMUVI. By car it’s the nearest castello to the capital on the southern side, and it’s all in getting around San Marino.

Test yourself

True or false?

0/3 Pick before you peek.

  1. Fiorentino is named after Florence.

    See the answer

    False. According to Wikipedia it comes from the Latin «florente», because of how wild the land was. It has no link with the Tuscan city.

  2. The first flight over San Marino ended in Fiorentino.

    See the answer

    True. In 1913 Gianni Widmer took off from Monte Carlo in a 50-horsepower Blériot, climbed to 1,600 metres and landed on the plateau after eleven minutes. A memorial marks it.

  3. Ruins survive of all three of Fiorentino's castles.

    See the answer

    False. There are ruins of Castellaccio and Pennarossa, but no trace remains of Torricella castle, according to the castello council.
