According to strict new rules that will enter into effect in April, tourists in Amsterdam's infamous red light district will have to turn their backs on the sex workers in windows.
Tour guides will have to ensure that visitors have their backs to the women who pose in full-length windows in brothels.
The strict new rules have been put in place by city authorities to crack down on the number of gawping tourists swarming the area.
Shouting, alcohol and drug use are also forbidden on the tours and visitors will no longer be allowed to take pictures.
Tour operators are also being ordered to tell sightseers to show 'respect' to sex workers and residents of the red light district.
