The entrance to the Antro del Corchia was found in an abandoned marble quarry, 860 metres above sea level. This entrance opens into an artificial tunnel, roughly 170 metres long, which leads to the true Karstic netherworld whose gateway is seemingly guarded by a stocky, conical stalagmite known appropriately as the Gendarme. Passing through the Franosa Gallery, we enter the Galleria degli Inglesi, where the eye is drawn to the whites and browns and rusty reds of the mineral formations. Not for nothing was it originally called the Painted Gallery, before its name was changed to remember the nationality of its first speleogists.
We pass through into the Galleria del Venerdi, where we find lava frozen imposingly into the form of an eagle with outstretched wings. From here we go through the thick fossil concretions of the Petrified Forests, before stumbling on a true marvel of nature in the spectacular Gallery of Stalactites. The walls are lined with them, one after the other, curving into little mirror like pools of water on the floor.
