The Ponte d'Ercole (locally also known as the Ponte del Diavolo) is an extraordinary geological formation located in the Frignano territory, nestled along the wooded ridge between the municipalities of Polinago and Lama Mocogno. It is one of the most significant and historically fascinating natural monuments in the entire Appennino Modenese. The Ponte d'Ercole. Source: Wikipedia The structure consists of an imposing natural sandstone monolith, shaped over millennia by the erosive action of the elements. The block appears as a large single-span arch, approximately 33 metres long and 3 metres wide, suspended about 3 metres above the rugged ground below. Its shape so closely resembles a man-made bridge that it can be walked across entirely on its summit. The surrounding area holds considerable archaeological and anthropological importance: Ritual and Historical Site: Since protohistoric times (Ligurian and Celtic) and later in the Roman era, the site served as an important open-air place of worship and a crossroads for tribes ascending the ridge. Archaeological excavations nearby have unearthed votive offerings, coins, and ex-votos related to water cults and the deity Hercules, from whom the structure takes its name. Geology: The rock is part of the sandstone formations typical of this Apennine belt, characterized by a different resistance to erosion compared to the surrounding marly and clayey soils, which allowed for the isolation of this singular arch. This longer route starts from the Castello di Brandola, climbing through the woods and passing the ancient springs of Brandola. Once you reach Ponte Ercole, you can return via the same path or complete the loop indicated in the link. This route is more challenging than the short version due to the total distance (about 9 km) and the gradients. It does not present specific technical difficulties but is not recommended in bad weather or after heavy rain, as the clay-heavy ground becomes extremely slippery.
