The Museum of Finnish Architecture, founded in 1956, and the Design Museum Helsinki (founded in 1873) launched a project in 2021 to establish a new national museum of architecture and design. In 2024 the Museum of Finnish Architecture and the Design Museum Helsinki completed a merger, forming the Architecture & Design Museum. A new building will be opened in 2030. The Museum for Finnish Architecture maintains a collection of Finnish architecture and serves as a source of expert knowledge for everyone interested in architecture and the built environment. It has large collections of plans and drawings, photographs and scale models, in addition to a public special library.
