The Lago degli Idoli is the most important archaeological site in Casentino, where one of the most conspicuous testimonies of the Etruscan cult was collected. Located in Ciliegeta (1380 m s.l.m), south of the top of Mount Falterona and a few hundred meters from the Capo D'Arno spring, it is geographically the central point connecting the Tuscan and Emilian Apennines. In the VI century BC the Etruscans considered Mount Falterona sacred, and therefore threw their offers into the lake of Ciliegeta, near the sources of the Arno river. From 1838 until today, many Etruscan finds have been made, some of which are kept at the British Museum in London and at the Louvre in Paris.
