San Michele iron bridge is of considerable historical-architectonic interest, and it is the symbol of the industrial archaeology in Lombardy. It crosses the stretch of the river Adda which runs enclosed between two high banks of conglomerate reef (the so-called "ceppo"). The symmetry of shapes, base, pillars, abutments and archs, the elegance of its open forms which give the opportunity to enjoy beautiful views over the natural landscape and which have placed the bridge among the most significant engineering works at an international level. Planned and built in 1889 in the National Workshop of Savigliano and based on a technical project of the Eng. Rothlisberger, it opened an important artery favoring the exchanges between the regions of Lombardy and Veneto.
Crespi d'Adda village, founded by the cotton manufacturer
Cristoforo Benigno Crespi, who had recently built in the area a modern
cotton industry, represents the almost unique Italian case of a village
which came out of nothing to provide accommodation to workmen, clerks,
It is the classical example of the company paternalistic ideology where philanthropy, utopia, and economic interest get together according to the example of the English company towns within the workforce control project. Promoting a healthy and moral life and placing the community needs before the production needs would have avoided social claims, class struggles, and trade union organization. The strict system of social hierarchies is also represented by the organization of space: the factory lies at the geographical center, and from here two perpendicular axes branch off. The first one runs parallel to the river, goes along the factory up to the graveyard and separates the working spaces from the residential area, the spare time and the services; the second links the main body of the plant to the green square in front of the pinewood.
The residential buildings have been arranged in a regular manner, and the farther they are from the factory, the more prestigious they are. At first, from 1878, some big multifamily houses where built for the workmen, then, between 1889 and 1984, they began to build houses for one or two families, according to the model of the English cottages. The building of Crespi's villa began in 1894: it was planned as a castle with towers and merlons by the architect Pirovano; the year before the church planned by the architect Cavenaghi had been finished. Until 1925 other works completed the structure of the town like the graveyard, new cottages for the employees, the kindergarten, the clinic and the public wash house. The creation of this town which we can still see nowadays intact, derived from a project which placed the symbols of power one in front of the other in a privileged position: the villa-castle and the church.
After leaving the small lake of Olginate, the course of the river Adda becomes winding and forms a meander whose bend turned to the West delimits a marshy area called Isola della Torre and Isolone del Serraglio, in the Town of Brivio. Since it is situated along the main road S.S. n. 639, in the intermediate stretch between Calolziocorte and Cisano Bergamasco, it can be easily reached. The morphology of the territory is typically fluvial, since it is characterized by abundant alluvial deposits which determined its flat aspect. From an environmentalist point of view, this area is extremely interesting because there are no human agricultural or industrial settlements, and because it is biologically rich.
The town, mentioned by Manzoni, reflects itself in the stretch of river separating the lakes of Como and Garlate. In Caloziocorte there is a dyke holding back the waters of the lake in Garlate and regulating its flow into the lake of Olginate; the latter is a mere widening of the Adda flow.
