Liberty Island is a small uninhabited island in New York Harbor in the United States, best known as the location of the Statue of Liberty.
Though so called since the start of the 20th century, the name did not become official until 1956.
In 1937, by proclamation 2250, President Franklin D. Roosevelt expanded the Statue of Liberty National Monument to include all of Bedloe's Island, and in 1956, an act of Congress officially renamed it.
It became part of the National Register of Historic Places site Statue of Liberty National Monument, Ellis Island and Liberty Island in 1966.
The island was closed to the public after Hurricane Sandy in October 2012 until reopening on July 4, 2013. 
Early National Park Service years (1933–1982).
In 1933, President Franklin Roosevelt ordered the statue transferred to the National Park Service (NPS).
In 1937, the NPS gained jurisdiction over the rest of Bedloe's Island.
With the Army's departure, the NPS began to transform the island into a park.
The Works Progress Administration (WPA) demolished most of the old buildings, regraded and reseeded the eastern end of the island, and built granite steps for a new public entrance to the statue from its rear.
The WPA also carried out restoration work within the statue, temporarily removing the rays from the statue's halo so their rusted supports could be replaced.
Rusted cast-iron steps in the pedestal were replaced with new ones made of reinforced concrete; the upper parts of the stairways within the statue were replaced, as well.
Copper sheathing was installed to prevent further damage from rainwater that had been seeping into the pedestal.
The statue was closed to the public from May until December 1938.
During World War II, the statue remained open to visitors, although it was not illuminated at night due to wartime blackouts.
It was lit briefly on December 31, 1943, and on D-Day, June 6, 1944, when its lights flashed "dot-dot-dot-dash", the Morse code for V, for victory.
New, powerful lighting was installed in 1944–1945, and beginning on V-E Day, the statue was once again illuminated after sunset.
The lighting was for only a few hours each evening, and it was not until 1957 that the statue was illuminated every night, all night.
In 1946, the interior of the statue within reach of visitors was coated with a special plastic so that graffiti could be washed away.
In 1956, an Act of Congress officially renamed Bedloe's Island as Liberty Island, a change advocated by Bartholdi generations earlier.
The act also mentioned the efforts to found an American Museum of Immigration on the island, which backers took as federal approval of the project, though the government was slow to grant funds for it.
Nearby Ellis Island was made part of the Statue of Liberty National Monument by proclamation of President Lyndon Johnson in 1965.
In 1972, the immigration museum, in the statue's base, was finally opened in a ceremony led by President Richard Nixon.
The museum's backers never provided it with an endowment to secure its future and it closed in 1991 after the opening of an immigration museum on Ellis Island.
Beginning December 26, 1971, 15 anti-Vietnam war veterans occupied the statue, flying a US flag upside down from her crown.
They left December 28 following a Federal Court order.
The statue was also several times taken over briefly by demonstrators publicizing causes such as Puerto Rican independence, opposition to abortion, and opposition to US intervention in Grenada.
Demonstrations with the permission of the Park Service included a Gay Pride Parade rally and the annual Captive Baltic Nations rally.
A powerful new lighting system was installed in advance of the American Bicentennial in 1976.
The statue was the focal point for Operation Sail, a regatta of tall ships from all over the world that entered New York Harbor on July 4, 1976, and sailed around Liberty Island.
The day concluded with a spectacular display of fireworks near the statue.
Liberty Road is the commemorative way marking the victorious route of the Allied forces from D-Day in June 1944.
It starts in Sainte-Mère-Église, in the Manche département in Basse-Normandie, France, travels across Northern France to Metz and then northwards to end in Bastogne, on the border of Luxembourg and Belgium.
At each of the 1,146 kilometres, there is a stone marker or 'Borne'.
The first lies outside the town hall in Sainte-Mère-Église. 
A replica of the Statue of Liberty in Colmar, the city of Bartholdi's birth, was dedicated on July 4, 2004, to commemorate the 100th anniversary of his death.
It stands at the north entrance of the city.
The Bartholdi Museum in Colmar contains numerous models of various sizes made by Bartholdi during the process of designing the statue.
