Padjedijk
Until the end of the 19th century, Purmerend consisted almost exclusively of canals. Many of these canals were filled in to make way for modern means of transport.
Yet you can still find many references to the time when there were only a few dykes running through the centre and the boat was the main means of transport. Just look at the name signs in the city. Padjedijk (the pathway to the dyke) is an example of this.
