It is located in a customs warehouse of the 19th century. It was adapted for museum use in the second half of the 1980s. The hall also hosted exhibitions of conceptual art, international projects and solo exhibitions by Latvian and foreign artists.
Since February 2020 it is closed for the reconstruction of the building with the idea that the Arsenāls should be the home of a permanent display of Latvian art from the second half of the 20th century.
