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.
