Why come

Fiuggi sits in two parts on the slope of the Ernici mountains, ninety kilometers southeast of Rome. The upper town, the medieval Anticoli di Campagna at 747 meters, is the original village; the lower town, Fiuggi Fonte at 643 meters, grew up around the springs in the late nineteenth century and was renamed Fiuggi in 1911. The Acqua di Fiuggi is the reason for the second town: an oligomineral water that runs through ancient volcanic deposits and has been used since the fourteenth century to dissolve kidney stones.

Pope Boniface VIII attested to the cure in his own case; Michelangelo wrote that it had cured him of the only kind of stone he could not love. The Fonte Bonifacio VIII and Fonte Anticolana stabilimenti, set in landscaped park grounds, are the heart of the lower town. The upper medieval centro storico has stone houses on narrow stepped streets, the Collegiata of San Pietro, and views east across the valley toward Anagni.
