Kiel Canal
The Kiel Canal is a 98-kilometre (61 mi) long freshwater canal in the German state of Schleswig-Holstein. The canal was finished in 1914 and links the North Sea at Brunsbüttel to the Baltic Sea at Kiel-Holtenau. An average of 250 nautical miles (460 km) is saved by using the Kiel Canal instead of going around the Jutland Peninsula. This not only saves time but also avoids potentially dangerous storm-prone seas.
Besides its two sea entrances, the Kiel Canal is linked, at Oldenbüttel, to the navigable River Eider by the short Gieselau Canal.
History
The first connection between the North and Baltic Seas was constructed while the area was ruled by Denmark-Norway. It was called the Eider Canal, which used stretches of the Eider River for the link between the two seas. The Eiderkanal was completed during the reign of Christian VII of Denmark in 1784 and was a 43-kilometre (27 mi) part of a 175-kilometre (109 mi) long waterway from Kiel to the Eider River's mouth at Tönning on the west coast. It was only 29 metres (95 ft) wide with a depth of 3 metres (10 ft), which limited the vessels that could use the canal to 300 tonnes displacement.
