The Llobregat is the second longest river in Catalonia, Spain. It originates in Castellar de n'Hug (comarca of Berguedà ) at an altitude of 1,259 meters in the Serra del CadÃ, and ends in the Mediterranean Sea, in the municipality of El Prat de Llobregat, near Barcelona. The total length of the river is over 170 kilometers.
The river is heavily managed in its lower course and water that was previously lost to the sea is now pumped upstream to increase the natural flow, recharge the Llobregat Delta wetlands and control seawater incursion. At Martorell, the Roman Via Augusta crosses the river on the impressive Devil's bridge, which dates from the High Middle Ages in its current form.
