Klara Sjö

Klara Sjö is a canal in central Stockholm, Sweden.

Separating the island Kungsholmen from the northern city district Norrmalm, the canal connects Barnhusviken to Riddarfjärden. Together with Barnhusviken, Karlbergssjön, and Karlbergskanalen, it thus forms part of the nameless body of water which separates Kungsholmen from the mainland districts north and east of it, Norrmalm and Vasastaden.

Four bridges stretches over the canal: Stadshusbron, Klarabergsviadukten, Kungsbron, and Blekholmsbron; the first of which limit the maximum height in the canal to 3.3 m.Several prominent buildings are located near the canal: Most notably the Stockholm City Hall south of it, but also the Seraphim Hospital on the western shore, in operation 1752-1990.The name of the canal is derived from the vicinity to the Klara district, in its turn named after a former monastery dedicated to Saint Clare.
