リバティ島
The New York City borough of Manhattan contains numerous smaller islands in addition to the main island of Manhattan. Three of these islands, Ellis Island, Governors Island, and Liberty Island, are located in Upper New York Bay, though jurisdiction of Ellis Island is shared with neighboring Jersey City, New Jersey, and Liberty Island is an exclave of Manhattan within New Jersey. There are also several islands in the East River, including U Thant Island, Roosevelt Island, Mill Rock, and Randalls and Wards Islands, which are legally part of Manhattan.
