Amsterdam is world famous for its red light districts. That's right, districts, there are actually three. The largest, oldest, and most famous is De Wallen. The Oude Kerk, as you may learn on a tour of Amsterdam, is well-placed in the center of De Wallen. The main streets have coffeeshops and pubs. The small alleyways that line the main canals contain rooms where women display themselves in front of windows lit with red lights. One of the most important rules in the red light district is DO NOT take pictures of the ladies in the windows. They will not hesitate to destroy your camera, and maybe worse. The other red light districts are Singelgebied and Ruysdaelkade.
