The Nicholas Roerich Museum is a small institution on Manhattan's Upper West Side dedicated to the work of Russian-born painter Nicholas Roerich (1874-1947). It traces its roots to the Master Institute and Roerich Museum that Roerich founded in New York in the early 1920s; after that institution closed during the Great Depression, board member Sina Fosdick helped re-establish it in 1949 in a brownstone on the Upper West Side, where it remains today. The museum holds more than 150 of Roerich's works across three floors, including landscape paintings from his final decades in the Kullu valley of the Western Himalayas, along with drawings, archival documents, photographs, and correspondence. It also promotes Roerich's advocacy for cultural-heritage protection through the Roerich Pact and hosts recitals and an annual poetry prize. Admission is free.
