In the north of Amsterdam there's the industrial area of the NDSM wharf.
Every summer there's a great theatre festival, Over t Ij.
Various performances in raw surroundings, with a view on the docks.
My favorite one was 'Van hier naar daar' (from here to there), in a cargo container. You were asked to write a letter about a memory, in a lovely post-office setting. On beautiful paper and with a fountain pen. Today I received on my doormat someone else's memory!
