Statue of Liberty National Monument is a national monument comprising Liberty Island and Ellis Island. It includes the Statue of Liberty, situated on Liberty Island (40°41′24″N 74°02′44″W / 40.689978°N 74.045448°W / 40.689978; -74.045448), and the former immigration depot on Ellis Island (40°41′57″N 74°02′23″W / 40.699300°N 74.039655°W / 40.699300; -74.039655). The Statue of Liberty was dedicated in 1886. The immigration station at Ellis Island opened in 1892 and closed in 1954.
President Calvin Coolidge used his authority under the Antiquities Act to declare the statue a national monument in 1924. In 1937, by proclamation 2250, President Franklin D. Roosevelt expanded the monument to include all of Bedloe's Island, and in 1956, an act of Congress officially renamed it Liberty Island. Ellis Island was made part of the Statue of Liberty National Monument by proclamation of President Lyndon Johnson in 1965. The United States historic district, a single listing on the U.S. National Register of Historic Places, was designated in 1966. The monument is managed by the National Park Service as part of the National Parks of New York Harbor office. It has been closed indefinitely since Hurricane Sandy in October 2012.
Ellis Island, in Upper New York Bay, was the gateway for millions of immigrants to the United States as the nation's busiest immigrant inspection station from 1892 until 1954. 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. A 1998 United States Supreme Court decision found most of the island to be part of New Jersey. The south side of the island, home to the Ellis Island Immigrant Hospital, is closed to the general public and the object of restoration efforts spearheaded by Save Ellis Island. The island has been closed to the public since Hurricane Sandy in October 2012 with no re-opening date projected.
