In 1791, George Washington selected the site for the White House. Beginning with John Adams, every American President has occupied the White House, in Washington, D.C. It serves as the primary residence for the president and his family. It is also the primary workplace for America’s political leaders. This remarkable home has 132 rooms, 35 bathrooms, and six levels. It welcomes about 6,000 visitors every day. (RICHARD NOWITZ—GETTY IMAGES)
