- Washington, D.C.
Situated at the navigational head of the Potomac River, between Maryland and Virginia, it has an area of 69 sq mi (179 sq km). The site was chosen by George Washington in 1790 as a political compromise that satisfied both Northern and Southern states. Designed by Pierre-Charles L'Enfant, it is one of the few cities in the world planned expressly as a national capital. The federal government occupied it in 1800. British troops burned the city (1814) during the War of 1812. With the annexation of Georgetown in 1878, the city became coterminous with the District of Columbia. Significant buildings include the Capitol, White House, and Library of Congress. The Washington Monument, Lincoln Memorial, Jefferson Memorial, and Vietnam Veterans Memorial are among the most famous of the city's more than 300 memorials and statues. The Smithsonian Institution is in Washington, as are numerous other cultural and educational institutions and foreign embassies. The economy is based on national and international political activities, scientific research, and tourism.
