1. Cave chapel of Genga (Marche)
In 1971 a group of speleologists from Ancona discovered a complex system of remarkable karst caves in the municipality of Genga. The cave system, known as Frasassi grottos, is the largest in Europe. The grottos owe their name to the Hermitage Sanctuary of Santa Maria infra saxa, dug in the rock at the entrance of the caves, which pronounced by the locals over time became ‘frasassi’.
At about 1.5 km from the entrance of the main Frasassi cave is a cavity called Grotta del Santuario, inside which is the Tempietto del Valadier, a chapel designed by the neoclassicist architect Giuseppe Valadier in 1828 for Pope Leo XII. The Chapel with octagonal plan was constructed with white travertine blocks, which were quarried inside the cave.
