Overview: The Washington Monument is closed until Spring 2019. The Washington Monument dominates the United States Capital skyline as a symbolic tribute to George Washington's military leadership, humble statesmanship, and Presidential fortitude and wisdom. Constructed from marble, granite and gneiss, the Monument is the world's tallest free-standing stone structure, towering more than 555 feet (169 meters). Plans for a national monument began as early as 1783 when the Congress passed a resolution to erect an equestrian statue to honor George Washington. Construction started in 1848 and faced continuing construction challenges due to political turmoil and a lack of funds. The U.S. Army Corps of Engineers completed the Monument's construction in 1884, and along with the Washington National Monument Society, opened it to the public in 1888. Visitors enter the Monument and then ascend via elevator to the 500-foot level to behold sweeping views of the city. Captivating exhibits on the 500-foot and 490-foot levels illuminate the contrast between historic photographs and modern views, while inviting you to learn more about Washington the man, the engineering marvel of the Monument, and the design of the city named in his honor. On descent, visitors have the unique experience of viewing selected commemorative stones expressing the sentiments of generations past awed by Washingtons impressive leadership.
