In 1937, France hosted the International Exhibition of the Arts and Techniques of Modern Life. Each country builds its own pavilion and the Soviet Union adorns its own with sculptures made by Joseph Tchaikov, a figure of Soviet realist art. In this architecture, which has become a work of propaganda, the eleven figures each represent an allegory of a Soviet republic and testify to the immensity of the country. Following the International Exhibition, the Soviet Union donated the sculptures to the Metalworkers' Union, which placed them on its property in Baillet-en-France. In 2009, excavations conducted in the park of the castle allow the rediscovery of these sculptures.
