The article examines ideological and institutional role of the “greening” policy in the Soviet urban planning practice of 1920-1930s. Relying on the example of the socialist city of Uralmash in Yekaterinburg (Sverdlovsk) the author traces how the idea of the “green city” affected the development of the urban settlement in terms of its functional mechanism and symbolic transformation. By analyzing the logic of the Uralmash “green” policy and its main narratives he argues that successful improvement of the post-Soviet green zones depends not so much on the new urban city-planning initiatives as on the new symbols and meanings that could give a clear vision of these spaces in the current social and cultural context.
