The United States Capitol Building on Capitol Hill, in Washington D.C., is one of the most iconic buildings in America. This building is literally on a hill, hints the name. When I first visited, I was shocked to learn that it has its own subway located inside. What is most interesting, is that Thomas Jefferson held a competition to choose an architect to design this building. Something special about this building is that one of my best friends works there and has taken me on a in-depth tour that most of the public can’t do.
