I've always been inspired by old industrial buildings like factories, but unfortunately such buildings have become rather rare in the Netherlands. At the moment you can still find some of the remains of the old harbour of Amsterdam called the ‘NDSM werf’ on the other side of the river ‘IJ,’ but this area seems to be in transition as well. For the time being the NDSM werf is a creative place where a lot of activities are taking place. The best part for me is the 'Y-helling' to enjoy the (modest) skyline of Amsterdam and to write graffiti.
The city's biggest flea market is hosted the first weekend of each month in and around a gigantic warehouse in the industrial area of NDSM in Amsterdam Noord. I love to snuff around the hundreds of stalls to find unusual props. Taking the boat to cross the IJ and leaving the old centre behind is very refreshing. Make sure to also have a drink in Noorderlicht while the sun sets.
