Subterranean Art Space
Dupont Underground: The Secret Transit Tunnels of Washington D.C.
Washington, District of Columbia, United States
Hidden beneath the pavement of Dupont Circle, this 75,000-square-foot former trolley station has lived many lives. Once a Cold War fallout shelter and a failed food court, it is now an industrial canvas for immersive art and sound installations.
Hidden beneath the busy intersection of Dupont Circle is a cavernous concrete world that most commuters walk right over without noticing. This subterranean labyrinth, spanning 75,000 square feet, has transitioned from a mid-century transit hub to a canvas for the city's creative underground.
Why It Stands Out
Built in 1949, this was the only underground station in Washington’s extensive streetcar network. After the trolley lines were retired in 1962, the space took on a series of strange identities.
It served as a designated fallout shelter during the height of the Cold War and, in a bizarre 1990s experiment, briefly housed a failed food court known as "Dupont Down Under." The food court was a disaster; the windowless, damp environment proved miserable for workers and unappealing to diners, leading to its closure in just months. Today, the gritty concrete walls are no longer home to fast-food stalls but to immersive light and sound installations.
The raw, industrial atmosphere—complete with lingering graffiti and remnants of past lives—provides a hauntingly beautiful backdrop for local artists to experiment with the tunnels' unique acoustics. It is a rare piece of preserved urban decay repurposed for the modern era.
Before You Go
Don't rely on your phone's GPS to find the door, as mapping apps often struggle with the subterranean coordinates. The entrance is tucked away on 19th Street, situated between a Starbucks and Cafe Dupont.
Because the space is a work in progress, the terrain can be rough. Expect to encounter uneven surfaces, occasional puddles, and debris, making sturdy, closed-toe shoes an absolute requirement.
Access is generally restricted to scheduled guided tours, which can be booked through the Dupont Underground website.
