CHECK IT OUT:
The European project RKM Save Urban Heritage (RKM stands for Rome Kiev Moscow) has FREE guided tours to visit Constructivist and Avant-garde architecture around Moscow. A little about them from their site:
The RKM_Guided Tours, organised by architects and urban anthropologists for RKM, examine social and architectural realities in the two target cities, highlighting the historical and cultural value of avant-garde heritage. Open to local citizens and students, the tours are based on an approach to research that looks at the relationships between urban space and examples of avant-garde architecture in the cities of Kiev and Moscow, in order to reveal the potential of these often-abandoned spaces, whose very existence is now at risk.
Next tour is coming up this Sunday (Oct 16), meeting at metro Aviamotornaya at 3pm.
