Great opportunity to learn about the history of the United States, it is worth doing the guided tour and do not miss the library!
Like any place in the United States, income is very strict, you can not enter liquids or food. They make you go through the metal detector. The guide warns that it is a very guarded place in which you must respect the rules.
The library and the Capitol are connected by an underground tunnel.
