Due to the status of USS Constitution as a commissioned ship of the United States Navy, it is required that all visitors pass through a security screening prior to entering the pier. Visitors will be asked to remove any bulky articles of clothing such as jackets, all jewelry, watches, belts, electronic devices including personal music players, PDA's, smartphones and cellphones, camera equipment, and all bags, luggage, or backpacks so that the items may be examined.

Please note any contraband will be confiscated and National Park police notified. Weapons are not allowed within both Boston National Historical Park and Pier One. Blades of less than two inches may be declared to security and will be returned if deemed safe. Federal officials who wish to carry within the yard must declare possesion of firearms and provide credentials.
