The Tsentrosoyuz Building is one of Moscow's important pieces of early modern architecture, designed by Le Corbusier with Nikolai Kolli and completed in the 1930s. Its long glass facade, ribbon windows, pilotis, and flat roof brought international modernism into the Soviet capital on a large scale.
It is still an office building rather than a museum, so the visit is mainly an exterior stop. Architecture fans will want to see how its severe lines sit among the heavier streetscape around Myasnitskaya Street.
