<<The Washington Monument was originally intended to be located at the point at which a line running directly south from the center of the White House crossed a line running directly west from the center of the Capitol. Pierre (Peter) Charles L'Enfant's 1791 "Plan of the city intended for the permanent seat of t(he) government of the United States ..." designated this point as the location of the equestrian statue of George Washington that the Continental Congress had voted for in 1783. However, the ground at the intended location proved to be too unstable to support a structure as heavy as the planned obelisk. The Jefferson Pier, a small monolith 390 feet WNW of the Monument, now stands at the intended site of the structure.
Excavation for the foundation of the Monument began in early 1848. The cornerstone was laid as part of an elaborate Fourth of July ceremony hosted by the Freemasons, a worldwide fraternal organization to which Washington belonged. Speeches that day showed the country continued to revere Washington. One celebrant noted, "No more Washingtons shall come in our time ... But his virtues are stamped on the heart of mankind. He who is great in the battlefield looks upward to the generalship of Washington. He who grows wise in counsel feels that he is imitating Washington. He who can resign power against the wishes of a people, has in his eye the bright example of Washington."
Construction continued until 1854, when donations ran out. The next year, Congress voted to appropriate $200,000 to continue the work, but rescinded before the money could be spent. This reversal came because of a new policy the society had adopted in 1849. It had agreed, after a request from some Alabamians, to encourage all states and territories to donate commemorative stones that could be fitted into the interior walls. Members of the society believed this practice would make citizens feel they had a part in building the monument, and it would cut costs by limiting the amount of stone that had to be bought. Blocks of Maryland marble, granite and sandstone steadily appeared at the site. American Indian tribes, professional organizations, societies, businesses and foreign nations donated stones that were 4 feet by 2 feet by 12–18 inches. One stone was donated by the Ryukyu Kingdom (Okinawa) and brought back by Commodore Matthew C. Perry, but never arrived in Washington. Many of the stones donated for the monument, however, carried inscriptions which did not commemorate George Washington. For example, one from the Templars of Honor and Temperance stated "We will not buy, sell, or use as a beverage, any spiritous or malt liquors, Wine, Cider, or any other Alcoholic Liquor." It was just one commemorative stone that started the events that stopped the Congressional appropriation and ultimately construction altogether. In the early 1850s, Pope Pius IX contributed a block of marble. In March 1854, members of the anti-Catholic, nativist American Party—better known as the "Know-Nothings"—stole the Pope's stone as a protest and supposedly threw it into the Potomac. Then, in order to make sure the monument fit the definition of "American" at that time, the Know-Nothings conducted an illegal election so they could take over the entire society. Congress immediately rescinded its $200,000 contribution. The Know-Nothings retained control of the society until 1858, adding 13 courses of masonry to the monument—all of which were of such poor quality that they were later removed. Unable to collect enough money to finish work, they increasingly lost public support. The Know-Nothings eventually gave up and returned all records to the original society, but the stoppage in construction continued into, then after, the Civil War.
In 1876 [22 years later], the Centennial of the Declaration of Independence, Congress agreed to appropriate another $200,000 to resume construction. The monument, which had stood for nearly 20 years at less than one-third of its proposed height, now seemed ready for completion.>>
