Dalempoort is the last of the city gates still standing (on location). The medieval town had four of these gates. The Kanselpoort, Arkelpoort and Waterpoort gates were later replaced with coupures, that’s to say wide openings in the rampart. The Waterpoort gate has also been preserved, though it is now located in the garden of the Rijksmuseum in Amsterdam. Unfortunately, you cannot visit the inside of the Dalempoort gatehouse (people actually live there!) but you can walk through the gate opening to the riverside.
