The Dewey Monument is a memorial statue by Robert Ingersoll Aitken in San Francisco, California, located at the center of Union Square.

The monument was erected to honor Admiral George Dewey, a hero of the Spanish–American War, for his victory in the Battle of Manila Bay.

On May 14, 1903, Roosevelt officially dedicated the monument, which "commemorates the victory of Admiral George Dewey and the American fleet over Spanish forces at Manila Bay, the Philippines, on May 1, 1898, during the Spanish–American War" and also is a tribute to the sailors of the United States Navy.

[1][2] Robert Ingersoll Aitken was hired to sculpt a 9-foot (2.7 m) statue representing Nike, the ancient Greek Goddess of Victory in honor of McKinley and Dewey.

Timbers over 100 ft (30.5 m) long were shipped from Oregon to support the block and tackle system used to construct the monument.
