Founded in 2004 by architects Alenka Korenjak, Ana Čeligoj and Maša Cvetko, ProstoRož Cultural Association (prostor = space, roža = a flower) is a non-profit cultural organisation which explores degraded urban areas and proposes new solutions for their revitalisation. The Association's main project is the annual site-specific project ProstoRož, held in Ljubljana both within and outside the framework of the Spring Festival organised by CodeEp.
