The Washington Monument honors George Washington (1732–1799), the nation’s first president, and stands at the heart of the U.S. capital. Designed by Robert Mills and completed under the direction of Lt. Col. Thomas Lincoln Casey and the U.S. Army Corps of Engineers, it is built in the form of an Egyptian obelisk, evoking the timelessness of ancient civilizations. When it was completed in 1884, at 555 feet, 5 1/8 inches (169 meters), it was the tallest structure in the world, holding that title until the Eiffel Tower surpassed it in 1889.

Origins and Design
The geometric layout of Washington, D.C., designed by Pierre L’Enfant, reserved a prominent site for a monument to Washington at the intersection of lines radiating south from the White House and west from the Capitol. In 1833, the Washington National Monument Society formed to fund and build a memorial “unparalleled in the world.” After a decade of fundraising and design competitions, the Society selected Robert Mills’ ambitious 1845 plan: a 600-foot obelisk surrounded by thirty 100-foot columns.

Construction
Construction began on July 4, 1848, with a cornerstone-laying ceremony attended by President James K. Polk, Dolley Madison, Eliza Hamilton, George Washington Parke Custis, and future presidents Buchanan, Lincoln, and Johnson. By 1854, the monument had reached 156 feet before work stalled due to political infighting and lack of funds.
In 1876, Congress assumed responsibility for completing the monument. Casey’s first priority was strengthening the foundation, which took four years. Matching the original stone proved difficult—three different quarries ultimately supplied stone, resulting in the color variations visible today. The final height was set at 555 feet, ten times the base width, and Mills’ elaborate colonnade was abandoned in favor of a simple, clean obelisk form.

Dedication and Early Public Access
The monument was dedicated on February 21, 1885, one day before Washington’s birthday. Inscriptions on the aluminum cap commemorate key dates and individuals involved, with the east face bearing the Latin phrase Laus Deo (“Praise be to God”). The public first accessed the monument in 1886 via an iron staircase; a public elevator was added in 1888. Today, 193 commemorative stones from states, cities, civic groups, and foreign nations line the interior walls, including a marble slab from the Parthenon inscribed in Greek.
Modern History and Restoration
The steam elevator was replaced by an electric model in 1901. The National Park Service assumed jurisdiction in 1933. Major restorations occurred in 1934, 1964, 1998–2001, 2011–2014 (after earthquake damage), and 2016–2019 (elevator modernization).
