The gallery has been present on Belgrade’s cultural scene for more than 20 years. In this time it has infiltrated Belgrade’s artistic life and has become a part of its general cultural atmosphere. It is used as a place for art exhibitions (both group and individual) of renowned artists, both domestic and foreign, who also include professional reviews of arts critics. While most Belgrade galleries emphasize multimedia art, the Atrium Gallery focuses on contemporary painting, drawing, printing and sculpting. The Gallery is also used to organize literary and other annual exhibitions. As many as 20 to 24 exhibitions are organized a year.

Exhibitions of Milan Konjović, Vasa Pomorišac, Zdravko Mandić, Milan Stasević, Slobodan Sotirov, Cvetko Lainović, Milun Mitrović, Radomir Reljić and others have been exceptionally successful here. Apart from organizing exhibitions of the aforementioned artists and other already well-known artists, the Gallery is also open to young and talented creators. The activities of the Gallery are not only covered by various media organizations, but also permanently presented in Likovni zivot magazine. For certain exhibitions and occasions, events are accompanied by music and theatrical performances, forums, book promotions, and painting auctions. All exhibitions are accompanied by high-quality catalogues, which detail the work displayed.

Since 2006 the Gallery has received special support from the City of Belgrade Secretary of Culture. An Artistic council, whose members are renowned artists from the fields of painting and literature, has also been established.

The floor mosaic created by renowned artist Aleksandar Tomašević (1921-1968) is located in the central gallery. Tomašević took his main inspiring motif from old distaffs decorated with mirrors. Presenting ornamentation native to Serbia, the artist used only two varieties of stone available in the region – white marble from Venčac and Dalmatian stone from Sinj. The artist renewed and enriched his work by boldly incorporating square and rectangular mirrors into the composition, thus attaining the very specific visual effect that it has. In 1986, a team of painters, who were supervised by Dr. Gordana Tomašević, the artist’s wife, embroidered a fragment from the Prizren mosaic, following the style of the original artist.
