The highlight is the museum's collection of 65 original paintings by Nikolai Rerikh on the 2nd floor, mostly mountainscapes from the celebrated drifter's time in the Himalayas. The 2nd floor also has a room of 17th-century European (mostly Dutch) masters, a collection of icons and several rooms dedicated to 18th-to-19th-century Russian art. The 3rd floor has some wonderful pieces from the Soviet era.
