Hafenstrasse a street in St. Pauli, a quarter of Hamburg, Germany. St. Pauli, located in the Hamburg-Mitte borough is one of the 105 quarters of the city of Hamburg, Germany. Situated on the right bank of the Elbe river, the Landungsbrücken are a northern part of the port of Hamburg. St. Pauli contains a world famous red light district around the street Reeperbahn. A red-light district is a neighborhood where prostitution and other businesses in the sex industry flourish. The term "red-light district" was first recorded in the United States in 1894, in an article in The Sentinel, a newspaper in Milwaukee. Other mentions from the 1890s are numerous, and located all over the United States. The origin of the "red light" term is considered to be the red lanterns carried by railway workers (which were left outside brothels when the workers entered, so that they could be quickly located for any needed train movement) or the red paper lanterns (which were thought to be sensual) that were hung outside brothels in ancient China to identify them as such. The color red has been associated with prostitution for millennia; in the Biblical story of Rahab, a prostitute in Jericho, aided the spies of Joshua and identified her house with a scarlet rope, which saved her household from the massacre that a successfully besieged city usually suffered. During World War I, there were many brothels in Belgium and France; blue lights were used to indicate brothels for officers, red lights for other ranks. -see also Wikipedia- Thanks for looking Andreas
