Caglieron caves, in Breda of Fregona, near Vittorio Veneto, represent one of the most beautiful and fascinating natural spectacles in the province of Treviso: a unique and magical place, characterized by a series of caves that were formed over the centuries by the work of nature and man. The natural cavity consists of a deep gorge carved by the Caglieron stream over layers of calcareous conglomerate, sandstone and marl from the Middle Miocene.

There are also numerous waterfalls, several meters high, with huge potholes at the base. In the deepest part there are large calcareous concretions on the walls that partially close the vault, giving the whole the appearance of a cave. On the walls of the gorge there are large artificial cavities, obtained with the extraction of sandstone, the typical `dolza stone`.

The mining activity began around 1500, with the aim of providing material for the construction of jambs, architraves …, which can still be seen on the old houses and the ancient buildings of Vittorio Veneto. The extraction method used has left its mark, contributing to give shape to a fascinating and original set of cavities that develop along the ravine, at the bottom of which the stream flows swirling and noisy.

The caves of Caglieron have become over time one of the most popular attractions in the area, thanks to the possibility of visiting them through a path that descends along the artificial cavities, then runs suspended above waterfalls and potholes to return to the light and reconnect to an ancient and picturesque mill (15th century) now transformed into a tavern, which once exploited the waters of the Caglieron stream.

Due to the hardness of the water, moreover, particular concretions called `gours` and other free concretions like` pearls of cave’ made by granules and pebbles that are formed by subsequent deposition of limestone were formed on the soil. A temporary spring also flows into the cavity, with the formation of travertine. A narrow cave about 7 meters long has been found and has been found which ends a few meters from the surface of the ground.
