Langstrasse

Langstrasse (literally "long street") is a street and quarter in district 4 in Zürich. Langstrasse begins near the district courts and extends north-northeast to the train tracks of Zürich Hauptbahnhof. The following short segment of Langstrasse leads towards Limmatplatz in district 5. Langstrasse is also referred to as a general area including the street and its surrounding tertiary streets.
The quarter has a population of 10,500 on an area of 1.13 km². It is notorious as Zürich's red light district, with an above-average crime rate, drug dealing and brothels. It is also the most overtly multicultural spot in Zürich, with a rate of 42% foreign residents, among the highest in Zürich. Due to the problems in this district, the City Council approved the comprehensive project "Langstrasse PLUS" on 14 March 2001 to achieve an improvement in public order and safety.
As the historical quarter of factory workers during Industrialisation, Aussersihl is also the traditional center of socialist and communist agitation in Zürich, the Helvetiaplatz on Langstrasse being a traditional site of May Day manifestations.
Langstrasse is currently undergoing a process of gentrification in certain areas, spurring public debate both in the quarter and city-at-large regarding its social, spatial, and economic future.
