The Nicholas Roerich Museum is like a mini-Frick Collection but with a few exceptions–the museum is free, and all the artwork and artifacts were painted and discovered by Nicholas Roerich himself. Housed in this 3-story Upper West Side town house are over 200 works of art ranging from paintings of the Himalayas to scenes from historical references to sketches from his early days designing sets for Russian ballets like The Rite of Spring composed by Igor Stravinsky.
