South Lawn

The South Lawn at the White House in Washington, DC, is located directly south of the house, and is bordered on the east by East Executive Drive and the Treasury Building, and on the west by West Executive Drive and the Old Executive Office Building, and along its curved southern perimeter by South Executive Drive and a large circular public lawn called The Ellipse. Since the address of the White House is 1600 Pennsylvania Avenue NW, and the North Lawn faces Pennsylvania Avenue, the South Lawn is sometimes described as the back lawn of the White House.

The South Lawn presents a long north-south vista from the house. Open to the public until the Second World War, it is now a closed part of the White House grounds that provides a setting for official events like the State Arrival Ceremony as well as informal gatherings including the annual White House Egg Rolling Contest and staff barbecues. Marine One, the presidential helicopter, departs from and lands on the South Lawn.
