Top 20 Artificial Islands - Amazing Man-Made Islands

Treasure Island (USA)

The artificial island with the best name started off as a sandy shoal off the coast of San Francisco. The city decided the shoal was a hazard for boats, so construction on the island started in 1936, overseen by the U.S. Army Corps of Engineers. 25 million cubic yards were taken from all over the bay to make the island, which is a mile by a mile-and-half. It was completed in 1939, just in time for the Golden Gate International Exposition. After the exposition came to an end in September 1940, the Navy took it over and it became Naval Station Treasure Island. It was closed in September 1997 for civilian use.
