Since its establishment in Slovenia in 2003, the Gregor Podnar Gallery has been one of the most internationally vivid Slovenian commercial galleries. A frequent attendee of international art fairs like Art Basel, Art Basel Miami Beach, Frieze Art Fair London, Fiac Paris, etc., the gallery has brought not only Slovenian artists to greater international recognition but endorsed various artists from the greater Central and Eastern European region as well. In 2007, the gallery moved its main premises to Berlin, where it is based today.
Gregor Podnar led the Škuc Gallery in Ljubljana between 1997 and 2003 where he also established the gallery's commercial activity and its presence on the international art market.
Initially, the Gregor Podnar Gallery opened in Kranj as part of the DUM Association of Artists and in March 2004 the new gallery premises opened in the town's former industrial area with the inaugural exhibition Venture, featuring work by the selected artists of the gallery. In August 2005, Podnar rented a new exhibition space from the Municipality of Ljubljana and moved the gallery to Ljubljana.
In September 2007, Podnar joined a cluster of commercial international galleries in Galerienhaus Lindenstrasse 34–35 on the frontier between Berlin Mitte and Berlin Kreuzberg. The new venue was officially opened in November 2007 with the group exhibition Like to like I. and continued with Like to like II. Podnar curated both shows and presented all of the artists represented by his gallery.
Afterwards, Podnar continued with solo exhibitions of the most recent production of his artists, in which his curatorial strategy stayed recognisable and significant. Gregor Podnar Gallery in Berlin has now turned into the base of Gregor Podnar's activities. Since then, the space in Ljubljana predominantly functioned as a project room mostly for presentations of individual artistic positions.
The gallery presents internationally well-known and established artists mostly from Eastern European centres, as well as young emerging artists from a wider context. These include Attila Csörgő, Vadim Fishkin, Alexander Gutke, Irwin, Tobias Putrih, Nika Špan, Primož Bizjak, Tomaž Gregorič, Miha Knific, Bogoslav Kalaš, Antal Lakner, Kazimir Malevič, Andrei Monastyrsky, Tadej Pogačar and Mladen Stropnik.
Since 2003, the gallery is frequently present on the most prominent international art fairs. Starting with Art Forum Berlin and Artissima Turin, Gregor Podnar attended Liste, The Young Art Fair in Basel, ViennaFair, and Arte Fiera in Bologna. In 2006, Podnar participated on Art 37 Basel and since then his gallery entered the upper level of international art fairs such as Frieze Art Fair London, Art Basel and Art Basel Miami Beach. He also presented the work of his artists at Art Brussels and in Paris on Fiac Art Fair.
Since 2005, Gregor Podnar Gallery has been publishing monographs, books about specific projects and special editions by individual artists (Nika Špan, Vadim Fishkin, Tobias Putrih, Primož Bizjak and Attila Csörgő).
