Metelkova is Ljubljana’s autonomous cultural centre, a former army barracks transformed into a colourful, graffiti-covered warren of clubs, bars, galleries and studios. By night its venues host everything from punk and metal to techno and reggae, drawing an alternative, bohemian crowd to one of the most vibrant and unconventional nightlife spots in the region. Covered in murals and mosaics and buzzing with creative energy, it is a must for anyone seeking the city’s edgier, underground side.
