Landwehr Canal

The Landwehr Canal, or Landwehrkanal in German, is a 10.7-kilometre (6.6 mi) long canal parallel to the Spree river in Berlin, Germany, built between 1845 and 1850 according to plans by Peter Joseph Lenné. It connects the upper part of the Spree at the Osthafen (Eastern Harbour) in Friedrichshain with its lower part in Charlottenburg, flowing through Kreuzberg and Tiergarten.

Lenné designed a canal with sloped walls, an average width of 20 m (66 ft) at the surface and locks near both ends to control the water depth. In the course of two enlargements (1883–1890 and 1936–1941), it reached a breadth of 22 m (72 ft) and a depth of 2 m (6.6 ft). Today the waterway is mainly used by tourist boats and pleasure craft.

The Landwehr Canal leaves the Spree River in the Osthafen (Eastern Harbour) in Friedrichshain, east of the city centre. It immediately descends through the Schleusenufer (Upper Lock) and heads in a straight line south west to its junction with the Neukölln Ship Canal, which provides a connection to the Teltow Canal. Here the Landwehr Canal turns north west through Kreuzberg, along the Paul-Lincke-Ufer

In Kreuzberg the canal passes the entrance to the former Luisenstadt Canal that, between 1852 and 1926, provided a further connection to the Spree River. Although this has since been filled and partially converted to a public garden, its route can still be traced by the parallel flanking streets with their distinctive damm suffixes.

Further west in Kreuzberg, the canal is paralleled for about 1 kilometre (0.62 mi) by the U1 line of the Berlin U-Bahn, which runs here as an elevated railway. After passing the elevated Möckernbrücke and Hallesches Tor stations, the U1 crosses the canal on a high level bridge that also spans the railway bridge that once gave access to the, now demolished, Anhalter Bahnhof. Shortly after that, the elevated U2 line crosses the canal.
