Venue

7A Posthuset, Central Stockholm

Located just a stone's throw from Stockholm Central Station, 7A Posthuset is a stunning building built in 1903 and used to house the Swedish postal service but was later converted into a spacious conference center. Midnight Sun has been held at this location since 2020.
