Commemoration of the American Revolution typifies the patriotic sentiment surrounding the American Revolution and the desire to preserve and honor the "Spirit of '76". As the founding story of the United States, it is covered in the schools, memorialized by a national holiday, and commemorated in innumerable monuments. Thus Independence Day (the "Fourth of July") is a major national holiday celebrated annually. Besides local sites such as Bunker Hill, one of the first national pilgrimages for memorial tourists was Mount Vernon, George Washington's estate, which attracted ten thousand visitors a year by the 1850s.
