L'Enfant Plaza is a complex of four commercial buildings grouped around a large plaza in the Southwest section of Washington, D.C.. Immediately below the plaza and the buildings is the "La Promenade" shopping mall. The plaza is located south of Independence Avenue SW between 12th and 9th Streets SW. It was built perpendicular to L'Enfant Promenade, a north-south running street and pedestrian esplanade part of which is directly above 10th Street SW. The plaza is named for Pierre (Peter) Charles L'Enfant, the architect and planner who first designed a street layout for the capital city.
