Ellis Island
Ellis Island is a federally owned island in New York Harbor, situated within the U.S. states of New Jersey and New York. Ellis Island  was once the busiest immigrant inspection and processing station in the United States. From 1892 to 1954, nearly 12 million immigrants arriving at the Port of New York and New Jersey were processed there. It has been part of the Statue of Liberty National Monument since 1965 and is accessible to the public only by ferry. The north side of the island is a national museum of immigration, while the south side of the island, including the Ellis Island Immigrant Hospital, is open to the public through guided tours.
