The capitol of the world's most powerful nation is totally void of skyscrapers. What it lacks in tall buildings, it takes back in monuments and memorials. Washington DC is jam-packed with structures honouring dead presidents (and sometimes their wives); Washington Monument, Lincoln Memorial, Vietnam veteran memorial and so forth. The Smithsonian institute is huge here, and a visit to the American History Museum and Museum of Natural History was a must. And of course the Capitol Building and a certain white house.
