Ellis Island

en.wikipedia.org/wiki/Ellis_Island

Ellis Island was the gateway for millions of immigrants to the United States as the site of the nation's busiest immigrant inspection station from 1892 to 1954. The island was greatly expanded with landfill between 1892 and 1934. Before that, the much smaller original island was the site of Fort Gibson and later a naval magazine. It became part of the Statue of Liberty National Monument in 1965, and since 1990, hosts a museum of immigration run by the National Park Service. A 1998 United States Supreme Court decision found most of the island to be part of New Jersey.
