The collection includes painting, photography, video art, and installations. The works outline trends in contemporary art and provide an opportunity for perusal of its history. Some are purchases made in 2012 (after the opening of the Sofia Arsenal – Museum of Contemporary Art in 2011) and others represent donations by artists.
The digital photo and video documentation of the Art in Action Association and the Sofia Underground Festival was also donated. The collection itself comprises archives of artists and of important exhibitions within the museum programme, which fully enrich the concept of contemporaneity.
