The premier venue for 20th-century Russian art is this branch of the State Tretyakov Gallery, better known as the New Tretyakov. This place has much more than the typical socialist realist images of muscle-bound men wielding scythes and busty women milking cows (although there’s that, too). The exhibits showcase avant-garde artists such as Malevich, Kandinsky, Chagall, Goncharova and Popova.
In the same building as the Tretyakov, TsDKh, or Central House of Artists, is a huge exhibit space used for contemporary-art shows. A number of galleries are also housed here on a permanent basis.
