Even if you know absolutely zilch about Amsterdam, you would have heard about its Red Light District. De Wallen or De Walletjes is one of the most famous tourist attractions of the city. Tourists come here in droves (myself included!) to see women of all nationalities display their 'attractions' in big glass windows illuminated in red light. De Wallen, Singelgebied and Ruysdaelkade, form the Rosse Buurt or red light areas of Amsterdam.
Prostitution is legal in the Netherlands and was legalised in the year 2000. But it was not always so. A perusal of the country's history indicates that during the Middle Ages (ie 5-15 centuries AD), prostitution was tolerated as a 'necessary evil' but considered to be a dishonourable profession. In the 16th century, the city of Amsterdam started regulating prostitution. Only the police could keep a brothel. According to accounts dating back to 1413, these were confined to two streets in Amsterdam, Pijlsteeg and Halsteeg. Those who practiced prostitution elsewhere in the city were arrested and their clients fined.
