Constructivism

An avant-garde movement of the early 20th century that originated in revolutionary Russia with work by the sculptor Naum Gabo. Constructivism had an imaginative understanding of geometry, a vision of a new sense of space, and an enthusiasm for modern materials.

Architectural adherents included the brothers Alexander and Vladimir Vesnin, and Vladimir Tatlin, whose revolutionary but un-built tower commemorating the Communist International remains an icon of the period.
