Top 6 Caves フィアーノ・ロマーノでの

Slightly hidden and covered by bush but still interesting to observe along the way

The nature reserve extends over about a thousand hectares between the Tiber Valley and the Cornicolani Mountains, in the Roman Sabina. The landscape is hilly, with pasture areas, crops and fragments of woods, remnants of the original forests. The area is known for its botanical value and for karst phenomena such as caves and sinkholes, including the Pozzo del Merro, one of the deepest in the world. The reserve also preserves historical evidence, from prehistory to the Middle Ages.

The meri are very deep karst cavities. Easy path to follow. Start from the large Sant'Oreste car park, the one below the road. There are three of them, all close together. On the same path, a little further on, there is the church in the cave of Santa Romana, a beautiful place that deserves to be visited.

The Pozzo del Merro is a karst sinkhole located in the countryside north of Rome, between the Cornicolani Mountains in Macchia del Barco and Macchia di Gattaceca, in the municipality of Sant'Angelo Romano. According to initial studies by the University of Tor Vergata, the cavity is 392 meters deep, which is the maximum limit the measurements have reached. The probes launched since its discovery have not reached bottom, and the studies continue. This sinkhole has always been known to the locals. In 1890 it appears in the description of a tourist itinerary that leads from Rome to Sant'Angelo Romano, and is described as "a kind of chasm, at the bottom of which extends a small lake and whose very steep sides are covered with trees". https://www.sotterraneidiroma.it/sites/pozzo-del-merro

The Meri del Soratte are wells (three in total) that are connected to each other. Already known in the times of Pliny the Elder, these wells, according to him, are the gateway to the Kingdom of the Underworld.

This church was dedicated to the Saint of Todi. The peculiarity of this church consecrated in 1218 is that it was built inside a cave.
