I have more than once visited "The Castle" as the main building of the Smithsonian is often called. Starting here gives you perspective and a guide to just how much is covered in the entirety of the Smithsonian, with several additional buildings nearby. The history covers everything from Bobby Orr's skates to Dr. James Smithson's crypt. In addition, the gardens and outbuildings are beautiful most seasons of the year. Give your self plenty of time to spend here and then enjoy all the wonderful museums of the National Mall area.
