The Smithsonian’s National Postal Museum is located in the historic D.C. City Post Office building opposite Union Station. This free museum, which requires no advance tickets, showcases the largest and most comprehensive collection of stamps and philatelic material in the world. It features extensive exhibits on postal history, including the origin of stamps, the design of post boxes, and the evolution of mail delivery by stagecoach, railway, plane, dog sled, and truck. Interactive displays, such as a scavenger hunt and the chance to print and collect free stamps, make it particularly engaging for children and families. The museum is small, clean, and well-organized with two main exhibition floors. One hall is dedicated to stamps from the U.S. and many other countries, while the other covers postal history, including transportation before and during the world wars and the role of postal inspectors. Visitors can walk along a Colonial post road, browse a 1920s post office, and see mail vehicles. A third level provides a calm dining and rest area. Described as a beautiful, interesting, and fun must-see, it is considered one of the best museums in Washington, D.C.
