Preserving DCA’s rich history has always been a main priority for the Airports Authority. Passengers are invited to visit the Exhibit Hall in Terminal A to learn more about the airport's history.  The Exhibit Hall is located in the corridor connecting Terminal B to Terminal A and offers several unique museum-like exhibits including video presentations, a model of the original terminal, memorabilia from the airport’s original dining room and artifacts found during the preservation of the Abingdon Plantation.
