Centrum is the innermost district of Amsterdam and the Binnenstad (1012 postcode) is the innermost zone of Amsterdam-Centrum borough. At the north end of Binnenstad is Centraal Station, Amsterdam's main railway station. The spine of Binnenstad is the former course of the Amstel River, which once flowed northwards to its mouth where the station now is. Nowadays it's a major tram route from Centraal Station, down Damrak, across Dam square and onto Rokin. In addition to being a major thoroughfare, it cuts Binnenstad into two sides. The former left and right banks of the river.
Nieuwezijds (New Side) is the left bank. Running up the entire middle of it is the pedestrianised shopping strip of Nieuwendijk and Kalverstraat.
