President John Adams, the first official resident of the White House, moved into the house in November 1800. The house was still not quite finished after nine years of construction. (It was a government contract, after all.) In 200 years, the house has endured arson (by British soldiers in 1815), one plane crash, numerous redecorations and renovations, far too many mediocre presidents, and the midnight soliloquies of Richard Nixon. The exterior, a significant example of Federal architecture, remains much as it was in 1800. The guided tours of the famous first-floor rooms show off more historic memorabilia than you will ever be able to absorb.
The White House Visitor Center is located at 1450 Pennsylvania Avenue NW, between 14th and 15th Streets on Pennsylvania Avenue. The Visitor Center is inside the north end of the Department of Commerce Building.
