The city, which only allows prostitution in certain areas, also plans to spend 700,000 francs ($760,000) a year to keep the sex boxes running.
Jean-Marc Hensch, a business executive who heads a neighborhood association in another part of Zurich, said he hopes the sex boxes succeed because otherwise the prostitutes might return to his area. He also cited the disgusting lack of sanitation in other city areas where prostitutes and their clients defecate and urinate in the streets and gardens, or have sex in the open because they have nowhere else to go.
"It's an experiment,'' he said. "It was absolutely urgent to find a solution.''
The drive-in garages, or sheds, have no doors to shut and come equipped with an emergency call button on the passenger side of the structure that sets off a flashing light and a loud alarm inside an adjacent office building where the city will post social workers specially trained to provide a measure of security. The Zurich police say they will beef up patrols around the perimeter to protect the sex workers when they leave and enter.
