A gold-studded rock’n’roll museum shaped like a Tetris block has opened in Denmark’s Roskilde, a city best known for its eponymous music festival.

Two architecture firms with a fondness for capital letters – Copenhagen-based COBE and Dutch practice MVRDV – designed the four-storey, cantilevered structure around disused concrete warehouses on an industrial site.

The setting of the museum – called Ragnarock – is intended to reflect the rawness of rock music, while its scarlet red interiors, inspired by the velvety inside of a guitar case, convey the genre’s glam era.

‘Our aim with the design was to translate the special energy, image and attitude of rock and pop music into architecture,’ says COBE founder and creative director Dan Stubbergaard. ‘The building will introduce the audience to the world of rock music in a tangible way. It is an homage to rock and pop stars like Bowie, Hendrix and Jagger.’

Ragnarok also has a library, recording studios, workshop spaces as well as an outdoor music venue. It forms part of COBE and MVRDV’s transformation of Roskilde’s industrial area into a cultural and creative district, featuring a new HQ for Roskilde Festival.
