The famous monument built to honor the first President of the United States is the Washington Monument. Located in Washington, D.C., the monument was constructed to commemorate George Washington's leadership during the American Revolutionary War and his presidency. Designed by Robert Mills, the construction began in 1848 but faced interruptions and was completed in 1884. Standing at approximately 555 feet tall, it is an iconic obelisk made of marble, granite, and blue stone. The Washington Monument has become a symbol of American pride and serves as a major tourist attraction, offering panoramic views of the U.S. capital from its observation deck.
