San Pellegrino mineral water flows from a thermal spring at the foot of a dolomite mountain wall towering above the Brembo River in the Italian Alps. The town of San Pellegrino Terme is located near Bergamo some 25 kilometers northeast of Milan. The properties of San Pellegrino Sparkling Natural Mineral Water were renowned as early as the 12th century. Legend has it that Leonardo da Vinci visited the source while living in Milan. Da Vinci is credited with making the town of San Pellegrino famous. He wanted to try its “miraculous water,” and in 1509, dedicated extensive studies and penned a lengthy treatise to water. Use of the water for therapeutic treatment, however, did not begin until the 18th century, due to the difficulties in reaching its remote location. An analysis first done in 1748 demonstrates a composition that is surprisingly similar to that of today. In 1839, the San Pellegrino Spring has become a renowned tourist location. The spa was created, and one can now relax their ills in the tubs, showers, adjacent spotless marble rooms and plentiful recreation areas.
