Washington D.C. is situated on the east coast of the USA, along the banks of the Potomac River. The city has an area of just under 70 square miles, but it sure packs a lot in! Washington was founded as the nation's capital in 1791. As soon as you land here you get a sense of the power and history that this metropolis represents. Most visitors start at the National Mall, a two-mile green strip often referred to as "The Nation's Front Lawn". Clearly, there's no shopping to be done at this Mall. What it does offer is a sweep of the country's most famous monuments and museums, all in one place. Begin your tour of the Mall at the Zero Milestone, the proposed reference point for distances on all US maps. To the north, you'll see America's most famous residence, The White House. To the south stands the Washington Monument. Rising 555 feet, this marble obelisk is the centerpiece of the National Mall. The US Capitol Building, on top of Capitol Hill, is the nation's seat of federal government. Rest a while by the Reflecting Pool. Surrounded by America's most iconic tributes to its heroes and founding fathers, it's easy to let your mind wander back through the various chapters of America's history. Nestled in the trees is the Vietnam Veterans Memorial. Engraved in its walls are the names of tens of thousands of soldiers who lost their lives in the battlefields of Vietnam.
