The San Nicola Bridge, also known as the Old Bridge, is one of the most significant historical artifacts in San Pellegrino Terme. Built between 1430 and 1471, it is closely linked to the founding of the Augustinian convent of Piazzo and the subsequent construction of the Church of San Nicola.
Originally, the bridge consisted of three arches supported by piers that rose in the bed of the Brembo River. Over the centuries, the structure suffered various damages due to the frequent floods of the river, which compromised its stability multiple times. The flood of 1783 was particularly severe, causing a partial collapse of the structure.
Following a new collapse caused by the 1842 flood, a major renovation was necessary. In 1843, the third arch was removed and the central one was widened, profoundly altering the bridge's original appearance and improving its resistance to the force of the water. Further consolidation work continued until 1856 thanks to the financial contribution of the municipalities of San Pellegrino, Piazzo Alto, Piazzo Basso, and Dossena.
Historical images also attest to the presence, in the center of the bridge, of a characteristic votive shrine, a sign of the deep religious devotion that accompanied the daily life of the local community.
Even today, the San Nicola Bridge represents a valuable testament to the history and urban development of San Pellegrino Terme, as well as being one of the most picturesque views of the town.
