Norrström, Stockholm

Norrström is one of the shortest rivers in Europe in central Stockholm. It connects Lake Mälaren with the Baltic Sea. It runs from Riddarfjärden, north of Gamla stan, to Stockholms ström (the western part of Saltsjön). Two islands lie within it, Strömsborg and Helgeandsholmen. It is one of two natural waterways between Mälaren and the Baltic sea, the other being Söderström south of Gamla stan. Norrström is crossed by Centralbron and the adjacent pedestrian bridge, Vasabron, Riksbron north of Helgeandsholmen which continues into Riksgatan and Stallbron south of the island, Norrbro crossing Helgeandsholmen, and Strömbron.
