The marble floor of the Rotunda is not only an eye-pleasing pattern; the marble tiles and rings symbolize the history of the United States until 1858, the year the floor was laid. The center pieces of stone represent the 13 original colonies. The three surrounding rings stand for territories gained by the U.S. as a result of the acquisition of the Northwest Territory, the Louisiana Purchase, and from the Mexican War. The sunburst pattern stands for the 32 states in the Union at the time. Finally, the outer band represents the U.S. Constitution which unites the country.
