Monte Calisio, Mountain summit in Prealpi Trentine, Italy

Monte Calisio is a summit reaching 1,097 meters in the Prealpi Trentine, rising prominently above the Val d'Adige and the city of Trento. The mountain displays varied terrain with dense woodlands, rock faces, and open areas that shape different hiking routes.

Austro-Hungarian forces began digging the underground fortification in August 1915 and finished in November, removing about 10,000 tonnes of rock. The H-shaped system joined a 250-metre gallery to a 160-metre one, with two armoured howitzer cupolas 68 metres apart. Below the summit at 829 metres stand the ruins of Forte Casara, built before the war and abandoned in 1915.

The silver mines here, known locally as canope, prompted Prince-Bishop Federico Vanga to establish one of Europe's first mining regulations in 1207. This code set rules for extraction and work conditions that governed operations at the time.

The mountain can be reached via several hiking paths, including routes starting from Villamontagna village and Rifugio Campel where parking is available. Visitors should wear sturdy footwear and check trail conditions, as the mountain can change significantly with seasons and weather.

A deer horn statuette called Venere del Gaban was discovered on the western slopes, representing the earliest evidence of human presence on the mountain. This small bone carving dates to prehistoric times and is now preserved in a museum collection.
