Great site with lots of devotion: Detailed maps of Amsterdam's red-light districts combined with pictures and useful articles for visitors, specially those who are on their first trip. It deals with many aspects that are unique to A'dam. The site includes guides to other Dutch RLDs like Alkmar and Haarlem. Belgian brothels from Gent, Brussels and The Hague are featured as well. This is one of the best bookmarks for Holland and Belgium.
