Cherry blossums near the Jefferson Memorial

Composed of circular marble steps, a portico, a circular colonnade of Ionic order columns, and a shallow dome, the building is open to the elements. Pope made references to the Roman Pantheon and Jefferson's own design for the Rotunda at the University of Virginia. It is situated in West Potomac Park, on the shore of the Tidal Basin of the Potomac River. The Jefferson Memorial and the White House located directly north, form one of the main anchor points in the area of the National Mall in D.C. The Washington Monument just east of the axis on the national Mall was intended to be located at the intersection of the White House and the site for the Jefferson Memorial to the south but soft swampy ground which defied nineteenth century engineering required it be sited to the east. The Jefferson Memorial is managed by the National Park Service under its National Mall and Memorial Parks division.
