From the royal pew of Ivan the Terrible, to Catherine the Great's use of landscape, to the struggles between the Orthodox Church and preservationists in post-Soviet Yaroslavl—across five centuries of Russian history, Russian leaders have used architecture to project unity, identity, and power. Church architecture has inspired national cohesion and justified political control while representing the claims of religion in brick, wood, and stone. The architectural vocabulary of the Soviet state celebrated industrialization, mechanization, and communal life. Buildings and landscapes have expressed utopian urges as well as lofty spiritual goals. Country houses and memorials have encoded their own messages.
