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