Get the babysitters number to hand!
This is such a brilliant initiative, in collaboration with Stockholm Stad and Stockholm Kulturliv. Kulturnatten Stockholm (Culture Night Stockholm) is the night you discover what you did not know or what you always dreamed of trying. For one night only, cultural institutions, galleries, theaters, museums, studios, games halls, libraries and much more open between 18:00 and 24:00 and invite you to an unforgettable evening. Look out for their trademark purple signs. All with free entrance.
You can download the full programme from their website, Kulturnatten Stockholm 2018.
