Cantinone caves

Guided visits: every day from Tuesday to Sunday at the time:
Morning: 10:30 – 11:30
Afternoon: 16:15 – 17:15 – 18:15

Cantinone’s caves wind for a stretch about 300 metres under the market place of the city and the Sanctuary of St. Joseph of Cupertino. Just climbed down, you will be fascinated to see the signs of man’s work in the friable sandstone walls. The rudimentary digging tools used suggest a widening of the galleries during the Middle Ages, but their origin could be much older and date back to the Romans and the Piceni, as suggested by the ancient wells with pedarole. In the crossroads we can feel a little bit disoriented, but in the past the principal goal was to dissuade and to disperse enemies in case of emergency. Don’t worry: the tour leader will show you a little trick to get it right road! The low-reliefs and pictures you can admire in the Cantinone’s Caves are mostly about religion and express a ritual use of cult. It is probably here, in fact, that friars came down to pray or to stay alone in the absolute silence, far away from the noise of the city. The symbolism, easy to recognize, and the walking in only one floor makes the visit suitable for everyone.

Piazza Dante caves

Booked guided visits on Saturday 11.15-12.15-17.00-18.00 and on Sunday morning 11:15-12:15.

On request you can book visits from Tuesday to Friday.

Climbing down to the ancient caves of the elegant “Fregonara Gallo Building”, behind the barrels, is possible to exceed the threshold of a subterranean world really suggesting: here the Piazza Dante’s caves. On two levels of depth, at 10,5 m from the square from which they take the name, these caves appear more recent than the Cantinone’s ones, but it will be surprising for the presence of enigmatic high reliefs and esoteric symbols, linked between the late eighteenth and early nineteenth century. In the buildings overlooking the square above, people have lived historically linked to the Carbonari and affiliated to Masonic lodges, as the Count Cesare Gallo. On the surface there is also Palazzo Campana, home of an important male college founded in the early eighteenth century that was certainly the vehicle of the Enlightenment’s thought in the city. It’s not hard to imagine why these noble and learned gentlemen climb down from their accommodation to meet in the circular room underground and perform rituals initiatory, away from prying eyes. During the Second World War  these caves, like others, were used as air-raid shelter here but what impresses most is reading the enormous amount of dates and names engraved on the walls as evidence of those difficult times.

Simonetti caves

Guided visits take place during special events or on request for groups of 15 people with few days in advance.

Hypogeums under Palazzo Hercolani Fava Simonetti is unique. It conserves inside the symbol of the “threefold belt”, probably the best preserved in Italy. It is said that the Templar knights use the cave to mark a holy place or to indicate the concentration of particular telluric energies. Between the crosses with eight tips there is a “patente cross” realized in bricks that appears embedded in the sandstone. More tracks seems to confirm the link to Jerusalemites and Hospitallers of Malta, orders descended from the Knights Templar, of which have been part of some members of noble families Sinibaldi Simonetti and residents in the building. Exploring the galleries, you will come across a small crack inside a niche located below the circular room in this cave. It’s fascinating to think how this could open allowing any followers to listen, but not to see in his face the participants of the meeting.

Simonetti’s cave is private propriety, so it is not artificially lighted as Cantinone’s and Piazza Dante’s caves and to visit it is suggested to bring a torch despite the tour is always guided and lighted by candels.

Riccioni caves

In July and August guided tours (Piazza Dante and Riccioni Caves):
Saturday at 15:30 – 17:00 – 18:30

Info and booking: 800228800

From the cellars in Palazzo Leopardi it is possible to enter one of the most interesting and better preserved caves of Osimo: the Grotte Riccioni.

Although not so extended, the cave is characterized by a very particular structure. Furthermore its symbols are strictly connected with Templars.

The star-shaped circular room at the end of the tour is unique. Inside you feel still the sense of mystery and secrecy, the same one once ministrants should perceive. Seated in their own places carved into sandstone, each one of them would have been able, from that position, only to listen to the others without looking at their faces.

The recess that once should be used by the watchman, the eight armed cross at the entrance, the face in high relief sculpted on the wall of the room are worth a visit.

That place, on which hundreds of years ago stood a Templar Domus, should have been once a meeting point for the members of that Sacred Order.

The cave belongs to Riccioni family and is not artificially lighted. Although there are only guided tours, we advise to carry a torch.”
