The Koller Gallery is a private art gallery located in the Castle District of Budapest, Hungary. Founded in 1953, it is the longest continuously operating private gallery in the country.
The galleryâÂÂs exhibition spaces extend over several floors, and the top floor houses a memorial room dedicated to the Hungarian-Italian sculptor Amerigo Tot.
The gallery was founded by the gallerist György Koller (1923âÂÂ1996), who established the Association of Hungarian Engravers (RMAK) in 1953.
In 1980, the gallery opened exhibition spaces in the former atelier-house of Amerigo Tot in the Buda Castle District.
In 1984, the gallery established a showroom and sales space in the Hungarian National Gallery, strengthening cooperation with public cultural institutions.
Over the decades, the gallery has organized exhibitions and contributed to the international presentation of Hungarian artists.
Artists exhibited by the gallery have included Amerigo Tot, Jenà  Barcsay, Miklós Borsos, Lajos Szalay, János Kass, Imre Varga and Miklós Melocco.
Since 1997, the Koller Prize, founded by Soós Szabó Edith, has been awarded annually to contemporary artists.
After the death of György Koller in 1996, the gallery remained under family management; in 2006, his grandson took over its leadership.
The gallery focuses on modern and contemporary Hungarian art. In addition to organizing exhibitions, its activities include art dealing, art appraisal, and advisory services for collectors.
Since 2021, the gallery has also organized auctions.
The gallery is situated in the historic Buda Castle District, one of the main cultural areas of Budapest.
The building previously served as the atelier-house of Amerigo Tot and remains closely associated with his work.
The upper floor of the gallery contains a memorial room dedicated to Amerigo Tot, presenting elements of his life and artistic legacy.
