What is the height of the Washington Monument in Washington, D.C.?

The Washington Monument is 555 feet 5⅛ inches tall.

The obelisk in Washington, D.C., honors George Washington, the first president of the United States and commander of the Continental Army. Its design was created by architect Robert Mills, and construction began in 1848.

Work stopped for more than two decades because of funding problems, political conflict, and the Civil War. When construction resumed, the color of the marble changed slightly, leaving a visible transition in the monument’s stonework. The monument was completed in 1884 and dedicated in 1885.

The Washington Monument was the world’s tallest building when it was completed, surpassing the Cologne Cathedral. It remained the tallest structure in the world until the Eiffel Tower was finished in Paris in 1889. The monument is a memorial, not Washington’s burial place; he is buried at Mount Vernon.
