Kulturnatt Stockholm in Stockholm
Stockholm's Kulturnatt opens more than 180 museums, galleries, libraries and cultural venues across the city for one free night each April, with most events running from 6pm to midnight. Running since 2010, the festival includes a free shuttle bus between the central T-Centralen hub and the island venues of Skeppsholmen, and a planning tool called My Culture Night to help visitors build a route through the hundreds of offerings.
