Osimo Underground Caves
Grotte di Osimo
A network of underground tunnels stretching several kilometres beneath the old town of Osimo, with walls carved with symbols and reliefs in the style of the Knights Templar and Freemasons.
Osimo is a hill town about 18 km south of Ancona. Beneath it lies a network of tunnels and caves of uncertain age, some of them dating back to Roman times or even earlier. The walls are carved with crosses, human figures and mysterious symbols, and the site has been linked to the Knights Templar and secret societies as a meeting place. The main caves open to visitors include the Palazzo Campana Underground Caves and the Grotte Riccardi. All require a guided tour. Weekend slots are more frequent, so booking ahead is advisable. Above ground, the old town has a Romanesque cathedral and a group of headless statues.
