Im Winkel, together with Gußstahlstraße, has been the red-light district of Bochum, Germany, since the early part of the 20th century.

[1] The local names for the street are "Eierberg", "Gurke" (cucumber, due to its length), "Riemenschleifer" (belt-grinder) or "Riemenwalzwerk" (belt rolling mill).

[3] The city of Bochum's restricted district ordinance of January 21, 2003 limits prostitution to Im Winkel.

On May 31, 2006, the Gelsenkirchen Administrative Court criticised that the wording of the ordinance did not describe the boundaries of the restricted area precisely enough.

Im Winkel is located in the Bochum-Mitte district, close proximity to the site of the mining group Bochum Association of West Park and the Centennial Hall.
