The National Cathedral is something like the 6th biggest church in the world which is way cool. It's Episcopalian which I think is something like the Anglican church back home. Anyway, it was really pretty, lots of stain glass windows and the like and we arrived to hear the choir sing.
It's built on the top of a hill so you can see the whole of DC. That little white dome is the Capitol Building. You can see the Washington Monument in this one
