Switzerland has long been famous for its mountaineering, chocolate and precision watches, but less is said about its prostitution, which has been legal since 1942.
Zurich is trialling open wooden garages, popularly called "sex boxes" by the Swiss media, which will be open for business for drive-in customers.
The publicly funded facilities - open all night and located away from the city centre - include bathrooms, lockers, small cafe tables and a laundry and shower.
Men will not have to worry about video surveillance cameras and the sex workers - who will need a permit and pay a small tax - will be provided with a panic button and on-site social workers trained to look after them.
