history
The city of Turin was established in Roman times at the point where it flows into the Po . The river has been used to generate energy since the Middle Ages , its water was passed through canals, so-called duriae , and was used, among other things, to operate mills.
In the course of the industrial revolution, especially in the 20th century, water quality has deteriorated drastically. It was not until the 1990s that an initiative to renaturalize the river was launched.
In 2002, the Parco agro-naturale della Dora Riparia landscape park was founded. Financed by the municipality of Collegno and the Piedmont region, an attempt is made to strike a balance between the demands of nature conservation and agriculture.
