291, Art gallery in New York
291 was an avant-garde art gallery that was opened in 1905 by photographer Alfred Stieglitz in New York City.
From 1905 to 1917, 291 was a place where many pioneering artists of its time were introduced such as Paul Cézanne, Pablo Picasso, and Constantin Brâncuși.
The gallery served as a center for progressive and modernist thought in American art during the early 20th century.
The gallery closed in 1917 and has no public access today, yet it is celebrated as the origin of modernism in America.
Despite its small size and life span, 291 significantly shaped the course of modern art.
