Calle Libre Festival in Vienna
Calle Libre is Vienna's international street art festival, bringing artists -- many from Latin America -- to paint large-scale murals live in public view over several days each spring. Guided urban art tours and workshops extend the program beyond the murals themselves, and the festival's past work remains visible across the city.
Jakob Kattner founded Calle Libre in 2014 after a study trip through Latin America, where he watched street art function as an accepted, even celebrated part of the urban landscape rather than something automatically treated as vandalism -- an idea he wanted to import into Vienna's relationship with graffiti and murals.
