The gallery was established in the course of the reconstruction of Bethlehem Chapel in the first half of the the 1950's. Its specialization has always been architecture and applied art exhibitions.
The gallery regularly exhibits works by Czech, European and global architects, especially those representing progressive middle and new generation studios. The gallery also boasts a long tradition of cooperation with a number of European architectural art galleries, centres and educational institutions. The gallery cooperates closely with artistic and technical universities, organizes international conferences and field trips, publishes expert literature, and organizes and hosts lectures and master classes related to the world of architecture. It also presents Czech works abroad and has organized several major exhibitions of contemporary Czech architectural design. Exhibitions highlight the work of renowned personalities, reflect contemporary issues, and present an overview of the architectural history of the 20th century. In recent years, the gallery has also organised exhibitions and festivals focused on public spaces, sustainable architecture, and the conversion and transformation of industrial heritage sites.
