Wright-Dunbar Interpretive Center is the western visitor center for Dayton Aviation Heritage National Historical Park. Two floors of exhibits, films, a recreation of the Wright brothers' printing office, a 1902 glider replica, and the Aviation Trail Parachute Museum connect the brothers' early work in printing and bicycles to practical flight and later aerospace parachute development. NPS lists public hours Wednesday–Sunday 09:00–16:00, with Monday–Tuesday closure and closure on Thanksgiving, Christmas and New Year’s Day. Ranger-led tours of the Wright Cycle Company Fourth Shop begin here. Visitor address: 16 South Williams Street, Dayton, Ohio 45402; contact 937-345-0433 for current park access and programmes.
