White House

All Hail the Chief. The home of U.S. Presidents since the 18th Century, the White House has been bombed (the War of 1812), bugged (Nixon, anyone?) and lionized as much as any building in the world. While terrorism concerns have closed public tours of the inside of the President's manse, you can still tour the gardens, including the famous South Lawn. For interiors, you're pretty much stuck with a sedated Jackie Kennedy or an indignant Martin Sheen. Check local listings.
