Ellis Island is a federally-owned island in New York Harbor that was the busiest immigrant inspection station in the United States. From 1892 to 1924, nearly 12 million immigrants arriving at the Port of New York and New Jersey were processed there under federal law. Today, it is part of the Statue of Liberty National Monument and is accessible to the public only by ferry. The north side of the island is the site of the main building, now a national museum of immigration. The south side of the island, including the Ellis Island Immigrant Hospital, is open to the public only through guided tours.
