The Oudezijds Voorburgwal, often abbreviated to OZ Voorburgwal, is a street and canal in De Wallen in the center of Amsterdam. The OZ Voorburgwal runs from the Grimburgwal in the south to the Zeedijk in the north, where it changes into the Oudezijds Kolk, which drains into the IJ.
The bridge over the OZ Voorburgwal between Damstraat and Oude Doelenstraat (bridge 204) forms a clear dividing line between the noisy northern Wallendeel and the quiet southern part. It is one of the most famous streets of the Red Light District, full of sex shops, window prostitutes, peep shows, brothels, bars and coffee shops. The Bulldog has several branches and a hotel here. The canal is also lined with monumental canal houses from the Dutch Golden Age, and the remains of the many monasteries that were located here in the Middle Ages.
