In 1791, Pierre L’Enfant envisioned the National Mall as a grand “public walk,” a sweeping promenade at the heart of the capital. But by 1900, his ambitious plan had been largely overlooked and altered. That changed with the influential McMillan Plan of 1902, which reimagined the ceremonial core of Washington, D.C., shaping much of what visitors see on the Mall today.
Take a walking tour through history and design to explore the Mall’s evolution—from its earliest conception to its most recent additions. Discover the story behind the once-planned museum park, the now-vanished railroad station and tracks, and the curious reason why the Mall doesn’t align with the compass.
Marvel at a rich tapestry of architectural styles represented by the Smithsonian buildings. Begin with the 1846 Castle, the first permanent structure on the Mall, and follow the architectural journey to the striking 2016 National Museum of African American History and Culture. Along the way, encounter the Gothic Revival Smithsonian Castle, the exuberant Victorian flair of the Arts and Industries Building, and the Beaux-Arts grandeur of the Natural History Museum.
Continue by comparing the distinct takes on Modernism in institutions such as the Hirshhorn Museum, National Museum of American History, National Air and Space Museum, National Museum of the American Indian, and the African American History and Culture Museum. The tour concludes with a glimpse at the Mall’s newest landmark, the Frank Gehry–designed Dwight D. Eisenhower Memorial.
The tour leader is Bill Keene, a lecturer in history, urban studies, and architecture.
