Most New Yorkers know Manhattan, but they have never heard of a small island on the North American coast that is the size of a tennis court, the Telegraph said.
The Telegraph said the island was close to the village of Alexandria Bay, known as the "Rum Island" or "island room".
The island has one house, a tree and a small beach, making it the smallest inhabited island in the world.
The island, an area of 30,000 square feet (about 2,500 meters), is called "Hope Island" before it was purchased in 1950 by the wealthy family of Seizeland.
The Seizeland family bought the island to build a small holiday home.
It is noteworthy that this island is one of the 1864 islands on the St. Lawrence River in New York, which constitute the "A Islands", located on the border between Canada and the United States.
