Step1
Decide which Smithsonian you would prefer to tour. Currently the Lunder Foundation Center and the Smithsonian Institute Building, the Castle offer tours.
Step2
Appear personally at the Luce Foundation Center information desk before 3 p.m. on the day you wish to have a behind-the-scenes tour of the Lunder Conservation Center. Tours leave from the third floor in the west wing of the Lunder Conservation Center every Wednesday afternoon at 3:00.
Step3
Be either a National Air and Space Museum member, a local resident or a Contributing Member of the Smithsonian if you want to tour the Smithsonian Institute's Castle. Tours are available by appointment only, and you must schedule two weeks in advance.
Step4
Reserve a tour in person by visiting the association desk at the Castle, or by calling (202) 633-2987 between 9 a.m.- 5 p.m., Monday - Friday. TTY users may dial (202) 633-5285. You also can email a request for a tour at castletours@si.edu. Include your name, tour date, home address, a local telephone number (such as the hotel you are staying at) and how many are in your party. Both phone reservations, and email requests must be made by noon the Friday before the tour.
