Ellis Island
Ellis Island, in Upper New York Bay, was the gateway for over 12 million immigrants to the U.S. as the United States' busiest immigrant inspection station for over 60 years from 1892 until 1954. Ellis Island was opened January 1, 1892. The island was greatly expanded with land reclamation between 1892 and 1934. Before that, the much smaller original island was the site of Fort Gibson and later a naval magazine. The island was made part of the Statue of Liberty National Monument in 1965 and has hosted a museum of immigration since 1990.
New York (state)
Ellis Island was the subject of a contentious and long-running border and jurisdictional dispute between New York State and the State of New Jersey, as both claimed it. The issue was settled in 1998 by the U.S. Supreme Court which ruled that the original island was New York State territory and that the balance of the added after 1834 by landfill was in New Jersey. The island was added to the National Park Service system in May 1965 by President Lyndon B. Johnson and is still owned by the Federal government as part of the Statue of Liberty National Monument. Ellis Island was opened to the public as a museum of immigration in 1990.
