Lafayette Square is a 6.97 acre public park located directly north of the White House on H Street, bounded by Jackson Place on the west, Madison Place on the east, and Pennsylvania Avenue to the south. The square and the surrounding historic townhouse structures were designated a National Historic Landmark District in 1970. Planned as part of the pleasure grounds surrounding the Executive Mansion, this square was originally called "President's Park", which is now the name of the larger National Park Service unit. The park was separated from the White House grounds in 1804, when third President Thomas Jefferson had Pennsylvania Avenue cut through east-west. In 1824, the park was officially renamed in honor of the Marquis de Lafayette, the Frenchman and military officer who fought in the American Revolutionary War. Lafayette Square has been used as a racetrack, a graveyard, a zoo, a slave market, an encampment for soldiers during the War of 1812, and many political protests and celebrations. Andrew Jackson Downing landscaped Lafayette Square in 1851 in the picturesque style.
The Ellipse
President's Park South is a park located just south of the White House fence. Properly, the Ellipse is the name of the five-furlong circumference street within the park. The entire park is open to the public, and features various monuments. The Ellipse is also the location for a number of annual events. D.C. locals can often be heard to say they are "on the Ellipse", which is understood to mean that the individual is on the field that is bounded by Ellipse Road. The park was conceived in 1791, the first plan for the park was drawn up by Pierre Charles L'Enfant, and during the American Civil War, the grounds of the Ellipse and incomplete Washington Monument were used as corrals for horses, mules, and cattle, and as camp sites for Union troops. The Army Corps of Engineers began landscaping work on the Ellipse in 1867 and worked on it through the late 1880s.
