The Thomas Jefferson Memorial is America’s foremost memorial to the nation’s third president. As an original adaptation of neoclassical architecture, modeled after Rome’s Pantheon, it is a key landmark in the monumental core of Washington, D.C., according to the National Park Service, which administers and maintains the memorial. The circular, colonnaded structure in the classic style was introduced to this country by Thomas Jefferson. Architect John Russell Pope used Jefferson’s own architectural tastes in the design of the memorial. Pope’s intention was to blend Jefferson’s contribution as a statesman, architect, president of the United States, drafter of the Declaration of Independence, adviser of the Constitution and founder of the University of Virginia. Few major changes have been made to the Memorial since its dedication in 1943. The most important change, of note, was the replacement of the plaster model statue of Thomas Jefferson with a bronze version of the same after World War II restrictions on the use of metals were lifted. Each year the Jefferson Memorial plays host to various ceremonies, including annual memorial exercises, Easter sunrise services and the ever-popular Cherry Blossom Festival.
