Ponte San Michele (also known as Ponte di Paderno or Ponte Röthlisberger) is a masterpiece of industrial archaeology from the late 19th century, located in Lombardy, which spans a deep gorge of the Adda river, connecting the municipalities of Paderno d'Adda (Lecco) and Calusco d'Adda (Bergamo). It was inaugurated in 1889. It was calculated by the Swiss engineer Jules Röthlisberger and built by the Società Nazionale Officine di Savigliano. It has an overall length of 266 meters and rises a good 85 meters above the river level. It is a single-arch bridge entirely in iron, riveted and without welds, built in the same historical period as the Eiffel Tower.

The Angelo Bertini Hydroelectric Power Plant is a gem of industrial archaeology located in Porto d'Adda (a hamlet of Cornate d'Adda, Monza and Brianza). Inaugurated on September 28, 1898, by the Edison group, it holds an extraordinary historical record: at the time of its construction, it was the most powerful hydroelectric power plant in Europe and the second in the world, surpassed only by that of Niagara Falls. Its original purpose was fundamental for the modernization of Milan, as it had to supply the energy necessary for the electrification of Milan's tram network, allowing for the definitive replacement of horse-drawn trams.

The bridge over the Muzza Canal, located in Lavagna (a hamlet of the municipality of Comazzo in the province of Lodi), is a historical landmark for crossing this ancient artificial waterway. The Muzza is a branch of the Adda river, known for being one of the oldest canals in Europe. Lavagna Lodigiana is a small rural village immersed in the countryside that develops right next to the canal. The bridge area is frequented by cyclists and hikers who travel along the Muzza cycle path or the Muzza-Ponte di Lavagna route, enjoying the river landscape.

The Muzza Canal is one of the most important and oldest hydraulic engineering works in Europe. It is a large artificial branch of the Adda river that crosses the Lombard plain. For centuries, it has represented the main resource for irrigating the lands of the province of Lodi and southern Milan. It originates in Cassano d'Adda (Milan), drawing water directly from the Adda near the Visconti castle. It ends its course after about 39-40 kilometers (over 60 km considering the entire main network), rejoining the Adda at Castiglione d'Adda (Lodi).

Unique wildlife oasis, perhaps the last of all ecosystems in urbanized areas. An environment to be respected and carefully maintained. I think of the devastation that routes D and C of the foothill highway will cause. Let's stop useless works and preserve what our territory still offers us.

The Muzza Canal is the oldest in Europe and this year, its 800th anniversary was celebrated by the Municipality of Paullo in collaboration with the Pro Loco and other Municipalities. Its origin dates back to the year 1220, when Frederick II of Swabia, crowned emperor of the Holy Roman Empire, issued an imperial edict that granted the people of Lodi the right to use the waters flowing through their territory. The current route, about 60 km long, receives the waters of the Adda at Cassano d’Adda, at an altitude of 120 m above sea level, crosses the Lodi territory for about 40 km up to near Castiglione d’Adda, at an altitude of 45 m above sea level, and here it releases them back into the Adda. It has a regulated water regime, with a flow rate, depending on the seasons, of about 200,000 liters of water per second; an initial width of 50 meters which reduces to a few meters at the end of its course and an average depth of 2 meters.

The Muzza canal (61 km long in total) is a branch of the Adda River and has recently celebrated its 800th anniversary, making it one of the oldest in Europe. Its name, with slight variations over the centuries, still recalls the Roman family Mutia who moved here in 90 BC, starting the first land reclamation works. Smaller watercourses branch off from the wide canal, winding through the countryside for a total length of about 1000 kilometers, mainly intended for agricultural irrigation. The surrounding landscape of countryside and farmhouses is evocative, with a succession of tree-lined rows and open fields. It is also very interesting from a naturalistic point of view as it attracts many aquatic birds that can be observed along the route.

Naviglio della Martesana is perhaps the least known of the ancient artificial canals connecting Milan to the great Lombard rivers. It originates from the Adda in Concesa, a hamlet of Trezzo d’Adda, crosses the Martesana sub-region, northeast of the provincial capital, and once in the city, it plunges underground beneath Via Melchiorre Gioia, at the height of Cassina de’ Pomm. It measures approximately 38 km in length, with a width varying from 9 to 18 meters. However, once upon a time, the Naviglio della Martesana continued in the open air all the way to the center, where a lock system centered on the Conca dell’Incoronata connected it to the short Naviglio di S. Marco and the urban network of the Navigli. The lock was inaugurated in 1496, utilizing lock gates designed by Leonardo da Vinci. The canal had been opened in 1471, under Francesco Sforza. By connecting it to the other Navigli, Leonardo laid the foundations for realizing a dream of the Sforzas: to travel by water from the Ticino, and therefore from Lake Maggiore, all the way to the Adda.
