<P> Between Sint Jansstraat and Sint Annenstraat and running parallel to them are Leidekkerssteeg, Gooijersteeg, Blaauwlakensteeg and Zwartlakensteeg . At least three of these had red light windows which were closed in the 1970s . Today these alleys are blocked by locked gates although the remains of some bricked over windows can be seen in the architecture . In the 1990s Slapersteeg was also closed and a gate now blocks the alley . </P> <P> In the 1990s parts of Sint Annenstraat and Sint Annendwarsstraat were demolished . The rooms in Goldbergersteeg were opened after this time . </P> <P> Prostitution is legal in the Netherlands, with the exception of street prostitution, but work permits are not issued in the form of a green card for prostitution; therefore legally working in the trade is limited mostly to EU citizens or foreign permanent residents . (A non-EU citizen can work legally in Netherlands without a work permit in certain circumstances, for instance, if they are the spouse of a local citizen .) From January 2013 the legal working age of a prostitute in the Netherlands was raised from 18 to 21 . </P> <P> Whilst health and social services are readily available, sex workers are required to undergo regular health checks at the government's expense . Brothel owners and room operators often require health certificates such as the SERVSAFE test before employing or leasing rooms . </P>
