The Red Light District consists of several canals, and the side streets between them, south of Central Station and east of Damrak. Known as ‘De Wallen’ (the quays) in Dutch, because the canals were once part of the city defences (walls and moats). Prostitution itself is limited to certain streets, mainly side streets and alleys, but the district is considered to include the canals, and some adjoining streets (such as Warmoesstraat and Zeedijk). The whole area has a heavy police presence, and many security cameras. Nevertheless it is still a residential district and has many bars and restaurants, and also includes historic buildings and museums — this is the oldest part of the city. The oldest church in Amsterdam, the Netherlands-gothic Oude Kerk on the Oudezijds Voorburgwal at Oudekerksplein, is now surrounded by window prostitution. The area has many sex shops and peep show bars. This section of town is a common attraction for bachelors celebrating a stag night, if you ever get hassled, a firm and loud “Leave me alone” will work most of the time.
