Even the story behind the building - a mix of 19th century baroque and bang-up-to-date modern - is an extraordinary one. Originally a theatre from the late 1800s, over the course of 150 years it became a venue for operettas, then a circus school, was partially demolished in the 1980s to be an indoor amusement park (which closed a few days later), and was left abandoned for over a decade.
Upcoming events include a festival with Berlin as its theme, a DJ Spooky weekend, and a host of concerts including Dan Deacon, Architecture in Helsinki and José González performing with the Göteborg String Theory.
Here are a few photos (I especially like the historic foyer that they've kept), and I've written an exhaustive article about the place on the HPRG blog here. Be sure to check it out!
