The U.S. Civil War further delayed construction of the Washington Monument until the project was taken up again in 1876, and Congress took over the funding and building of the monument. The U.S. Army Corps of Engineers completed construction of the 555 feet 5 1/8-inch obelisk on Dec. 6, 1884. A change in the color of the stone marks the different phases of construction because stone from the original quarry was no longer available after the delay, and a substitute had to be found. The Washington Monument was dedicated on Feb. 21, 1885, and it opened to the public on Oct. 9, 1888.
