In an effort to increase prostitutes’ safety and render their work less visible in public, Switzerland’s largest city has built a series of wooden garages known as “sex boxes” designed to provide customers the convenience of drive-in prostitution.

According to the Associated Press, Zurich’s publicly funded facilities are complete with bathrooms, lockers, cafe tables, laundry, and showers. There, customers have their choice of several dozen prostitutes that they can approach and negotiate with from the comfort of their cars. The sex workers are required to obatain a permit and pay a small tax; the government, which legalized prostitution in 1942, provides them with a panic button and an on-site social worker.

Zurich voters approved the creation of the sex boxes last year at a cost of $2.6 million in order to move prostitution out of the downtown area. The AP reports that the neighborhood “had become a public nuisance and safety concern due to lack of sanitation, aggressive men, and associated drugs and violence.”
