What is Fiuggi known for?

Oligomineral spring water bottled and drunk in the resort since the late nineteenth century, used to dissolve calcium-oxalate kidney stones. The pope of the Outrage of Anagni attested in his own case to the water's effect on kidney stones; Michelangelo later confirmed the same. Lower town built around the springs in the late 1800s, with Liberty-style pavilions, a 1924 grand hotel, and landscaped thermal parks.

Fiuggi is a comune in the province of Frosinone, Lazio region of Italy, about 81 kilometers from Roma.

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.

Fiuggi is a thermal town and works year-round. Most cures are taken in spring and autumn, when the air is mild and the springs are most pleasant to drink in the open. June through August brings the resort season: hotels fill with longer-stay guests, and the 747-meter elevation of the upper town offers a refuge from Roman heat. December through February is the quietest stretch, when the upper centro storico empties and the lower town runs at half capacity. The Festa di San Biagio in early February and the Palio delle Quattro Porte in summer are the main local festas.
