The cornerstone was laid on July 4,1848. At the outbreak of the Civil War, the monument stood at 176 feet height. Construction was halted in 1861 and was taken up again in 1876. One of the outstanding engineering feats of the Washington Monument is the pyramidion which sits astride the top of the shaft from the 470-foot to the 500-foot levels. The pyramidion is 55 feet in height. To complete the obelisk, the aluminium capstone was placed atop the pyramidion on Dec 6, 1884. The Washington Monument stood 555 feet tall. The dedication of the completed Washington Monument took place on Feb 22, 1885 (153rd birth anniversary of George Washington).
