Binnenalster (pronounced [ˈbɪnənˌʔalstɐ] ) or Inner Alster Lake is one of two artificial lakes within the city limits of Hamburg, Germany, which are formed by the river Alster (the other being the Außenalster). The main annual festival is the Alstervergnügen.

The lake has an area of 0.2 square kilometres (0.077 sq mi).[1]

History

The phrase "inner" refers to the old city walls of Hamburg. The Binnenalster was the part of the lake that was "inside" the city walls. The lake was originally created to serve as a reservoir for a mill.

During World War II, the Binnenalster got covered in camouflage to pose as another part of the inner city. The purpose of the mostly wooden covering was to make it harder for incoming bomber planes to navigate (in the hopes that the Binnenalster would get bombed instead of the actual inner city). A fake Lombardsbrücke was also added to the Außenalster together with an anti-aircraft unit.[2]

As of 2008 the old city walls do not exist, instead two car and train bridges, the Lombardsbrücke and the Kennedybrücke, span the river.

Location

The Binnenalster is bordered by embankment streets on three sides, only the northern side is bordered by a park. Jungfernstieg – on the southern side, opposite this park is a busy boulevard and center of the Binnenalster. Left and right, Ballindamm and Neuer Jungfernstieg accommodate a number of corporate headquarters and first class hotels.

Public events

Alstervergnügen

The Alstervergnügen (English: Alster enjoyment) is an annual street fair held around the lake. It always takes place throughout the first weekend of September, and offers a wide variety of food, drink, vending and games stands, as well as some rock bands.
