Look up in De Passage (The Passage) and you will see a few thousand hats floating above you.
The Hat Exhibition Chapeau! is being held in De Passage until mid-October (depassage.nl, article in English). As the story goes, a few years ago about 3,000 hats were found in a vacant space above the Ladies Paradise shop in De Passage. The shop itself closed around 1998-2000. The designer Pink Steenvoorden came up with the idea of hanging most of them from the ceiling for visitors to photograph.
You can view a picture of the interior of the shop at The Hague’s city archive.
If you will be around for Prinsjesdag, you can also take part in The Hague Hat Stroll 2022 on September 17. For more information see prinsjesfestival.nl (in Dutch). Everyone is asked to wear their prettiest hat. If you don’t have one, you can borrow one for the event from the supply of hats found in De Passage. The walk will go through The Hague’s Museumkwartier (the Museum Quarter [in English]).
