Lambro

The Lambro is a river in northern Italy, located in the Lombardy region. It is part of the Po River basin and originates in the Alpine foothills north of the Lombardy plain. The river generally flows southeast through the Brianza area and toward the Milan metropolitan region, traversing several municipalities that lie near or within the greater city’s outskirts. In its lower course the Lambro is connected to the Lombard drainage network that ultimately feeds the Po system.

The Lambro has a variable flow, with higher discharge in spring and after rainfall and lower flow during dry summers. Its waters have been affected by urbanization and industrial activity, leading to pollution concerns and habitat modification in the 20th century. In recent decades regional and local authorities have pursued restoration and river-management projects aimed at improving water quality, stabilizing flood risk, and re-establishing riparian habitats in parts of the river.

Historically, the Lambro has influenced settlement patterns and economic activity along its banks. The river’s presence has shaped local landscapes and has appeared in regional culture and literature. The toponym Lambro is of uncertain origin, with scholarly discussion suggesting pre-Roman roots and possible Latin or Celtic influences.
