Security and Policies
The safety of the Smithsonian's visitors, volunteers, staff, and collections is of the highest importance. As the nation's most beloved collection of museums and galleries, we work hard every day to ensure the preservation of our country's treasures for the enjoyment of generations to come.
When you visit any of the Smithsonian's buildings you will discover that we have security measures to ensure your safety and the safety of the objects contained within. You'll be greeted upon entry by one of our security personnel who will conduct a thorough but speedy hand-check of all bags, briefcases, purses, and containers.
At some museums, such as the Air and Space, American History, Natural History, Postal, and American Indian Museums, visitors are required to walk through a metal detector. Those who are unable to go through the metal detector will be hand-screened with an electronic wand by security personnel. Bag checks will be conducted via an x-ray machine at the Air and Space Museum and Postal Museum. At all other museums, bags will be checked by hand.
Because of the security measures, the lines for entry to the museums may be long during peak seasons and holidays. We ask for your patience, cooperation, and assistance in keeping America's treasures safe.
Tips for Visiting the Smithsonian
We ask that when you visit the Smithsonian that you help us to ensure our collections remain safe. Please consider leaving any items that need to be checked
by security at home or at the hotel to speed entry.
- Do not bring large daypacks, backpacks, or luggage into the museums, as they will be subject to a lengthy search in each building entered.
If possible, leave such items on the tour or school bus or in a hotel room.
- A reminder: no accommodations are available for eating bag lunches within the museums except in the Kogod Courtyard of the Reynolds Center for American Art and Portraiture.
- Do not bring any sharp items into the museums such as knives (including pocket or "Swiss Army"-style knives), screwdrivers, scissors, etc.
- Other items not permitted include firearms, pepper spray, and Mace.
