The Supreme Court of the United States is located in a beautiful building near the United States Capitol Building. In it, the nine Justices of the Supreme Court receive and debate cases that have some of the largest-reaching impact in the history of the United States.
You can get tours of the Supreme Court, which is one of the only ways to see the interior. During sessions, there is no live broadcast or video recording. Audio recordings are usually released much later than the oral arguments, but no video. Because of this, most people have only seen what the Supreme Court looks like through television or movies.
Additionally, if your timing is good and you enjoy watching legal proceedings, you can watch the oral arguments in person. This is also free, but you have to get there at specific times and the cases are not always interesting. However, if this suits your interests you can be there in person to watch history unfold in front of you.
