Thermalism in the Brembana Valley: history of a spring that has become a myth

There is a thread that has been running through the Brembana Valley for centuries: the’water.
Before the valley became a tourist destination, even before casinos and elegant establishments sprang up, there was a spring here that people had known about since the Middle Ages. A spring that healed, that attracted peasants, wayfarers and the sick, and that in time would transform San Pellegrino Terme into one of the capitals of Italian thermalism.

Ancient origins of the source

Historical sources attest that since the 13th century San Pellegrino mineral water was the object of small “pilgrimages.” It was drunk to relieve ailments, to purify the body, to seek relief.

Tradition has it that Leonardo da Vinci, engaged between 1482 and 1512 in studies of Lombard rivers, passed through the Brembana Valley and visited the spring. This is not a certain fact, but it is a legend that recurs in several publications and fits perfectly with his focus on waters and their behavior.

Early analysis and the first spas

The documented history of thermalism begins in the 1748, when the spring was first analyzed: the composition-rich in calcium, magnesium, sulfates and bicarbonates, with a fixed residue around 900-1100 mg/l-was surprisingly stable even in later centuries.

In 1760, Pellegrino Foppoli set up benches and structures around the spring for visitors to sit and drink. It is a simple gesture, but it represents the beginning of modern thermalism: the practice of curing oneself with mineral waters began to spread, especially among the nobility and bourgeoisie.

Between the 1842 and the 1848, the municipality granted exploitation rights to the Palazzolo family, with a clause that tells much about the era: some of the water was to remain free for the inhabitants, via an external conduit. Around the spring, the first real spas were thus born.

From the healing spring to the city of water

The turning point came between the nineteenth and twentieth centuries. In 1899 the San Pellegrino Spa Limited Company was born, turning the resort into an international destination:

• Beverage Room (1901), where visitors drank the therapeutic water directly;
• Grand Hotel (1905), a symbol of the Belle Époque;
• Municipal Casino (1907), one of Europe's finest Art Nouveau masterpieces.

It is the birth of a small Alpine Monte Carlo, where elegance, health and worldliness were intertwined on the banks of the Brembo River.

Today: the tradition that continues

The modern QC Terme San Pellegrino spa picks up this legacy.
Hot tubs, saunas, Kneipp paths, and relaxation lounges coexist with Art Nouveau colonnades, frescoed ceilings, and early 20th-century mosaics.

Thermalism is no longer “cure” in the 19th-century medical sense, but regeneration: slow wellness set in a place where history has not been erased but integrated in a refined way.
