Washington Monument - Charlotte and DC ?

So we went to Charlotte and Lorraine set up a private tour of the city. One stop was the

The Mecklenburg Monument which is smaller version of the Washington Monument. We were curious which was erected first. so here are the facts:

The Mecklenburg Declaration of Independence is a resolution allegedly proclaimed at Charlotte, North Carolina, by the Committee of citizens of Mecklenburg County on May 20, 1775. Proclamations and resolutions, such as the Fincastle Resolutions in the Colony of Virginia, by local groups throughout the American Colonies during 1774 and 1775 were common. No original text exists and no contemporary mention of it was made in North Carolina or in other colonies. The 1819 copy was said to be created from memory. Historians have yet to confirm the original document's existence.
May 20 was the day after news arrived of the battle of Lexington. The seal and flag of North Carolina bear that date. The citizens of Mecklenburg did adopt, on May 31, 1775, strong anti-British resolutions, declaring suspension from office of all crown officials. The Monuement was erected in June 1898.

The Washington Monument is a large, white-colored obelisk at the west end of the National Mall in Washington, D.C. It is a United States Presidential Memorial constructed for George Washington. The monument is among the world's tallest masonry structures, standing 555 feet (169.29 m) in height and made of marble, granite, and sandstone. It was designed by Robert Mills, a prominent American architect of the 1840s. The actual construction of the monument began in 1848 but was not completed until 1884, almost 30 years after the architect's death. This hiatus in construction was because of a lack of funds and the intervention of the American Civil War. A difference in shading of the marble, visible approximately 150 feet (45 m) up, clearly delineates the initial construction from its resumption in 1876.

Its cornerstone was laid on July 4, 1848; the capstone was set on December 6, 1884, and the completed monument was dedicated on February 21, 1885. It officially opened October 9, 1888. Upon completion, it became the world's tallest structure, a title it inherited from the Cologne Cathedral and held until 1889, when the Eiffel Tower was finished in Paris, France.
The Washington Monument reflection can be seen in the aptly named Reflecting Pool, a rectangular pool extending to the west, towards the Lincoln Memorial.
