Amsterdam is the most watery city in the world.
Its canals and harbours fill a full quarter of her surface
Its waterways have always been its essence and its source of wealth.
Amsterdam is the only ancient city in the world where the medieval center is not a museum but a Red light district. Already in the Middle ages, drinking houses were established around the first harbours in the city. The first brothels here were opened in the 15th century, mainly in the Warmoesstraat and the alleys around it. But along the first canals in the area, rich merchants and regents established residence.
