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. From Wikipedia
