Points of interest

TREZZO SULL'ADDA - The Visconti Castle
TREZZO SULL'ADDA - The Visconti Castle

Located on a promontory in a bend of the river, protected on both sides, the castle is one of the most important of Milan province. It was built in defense of a bridge and, due to its strategic position, it was always contested by the local nobility, often destroyed or burnt down but always rebuilt. The current ruins date back to the construction of the 1370 by Bernabò Visconti, of whom was the residence and prison until his death. The bridge was a single span of 72 meters, 25 meters high above the water, fortified and built on three levels. A very remarkable engineering work for its time. The castle had a 42 meters high square tower.


They were the real engine of the Lombardy economy at the beginning of the twentieth century, taking advantage of the water power of the river to turn it into energy. Among the most important stations stand the Bertini, Taccani, Esterle and Semenza ones, magnificent structures that still tell the relationship between water and man.


The small shrine is located on top of a rocky peak near Porto d'Adda, between the Paderno Canal and the river. Built in 1386 on the ruins of an ancient Lombard fortress, it housed a monastic community for centuries, before falling in neglect and be rediscovered only in 800. Fascinating for its location overlooking the river, the Sanctuary is a stage of St. Augustine Way, a walk pilgrim route, designed to connect twenty-five Marian shrines in the Brianza area.


Located in the Adda North Park and Adda di Leonardo Eco-museum, Paderno is a place that had its historical importance in the formation of the path along the river Adda. In the past, in fact, it constituted a bottleneck along the river, the problem was resolved only in 1700 with the creation of an artificial canal (naviglio) that runs parallel to the Adda (2.6 km long and over 11 meters wide, with a water height always higher than 1.20 m.), completed under the auspices of Maria Theresa d’Asburgo following the sixteenth-century projects of Leonardo da Vinci. In Paderno d'Adda there is also the picturesque bridge of San Michele (or Paderno bridge). Built between 1887 and 1889, it is 266 meters long and it has nine supports. The height on the river is about 85 meters.
