The Lower East Side Tenement Museum, located at 97 and 103 Orchard Street in the Lower East Side neighborhood of Manhattan, New York City, is a National Historic Site. The Museum’s two historical tenement buildings were home to an estimated 15,000 people, from over 20 nations, between 1863 and 2011. The museum, which includes a visitors’ center, promotes tolerance and historical perspective on the immigrant experience.

The Tenement Museum was founded in 1988 by Ruth J. Abram and Anita Jacobson. The Museum’s first key property, the tenement at 97 Orchard Street, was designated a National Historic Landmark on April 19, 1994. The National Historic Site was authorized on November 12, 1998. It is an affiliated area of the National Park Service but is owned and administered by the Lower East Side Tenement Museum.
