Check out the tunnels under Dupont Circle Wednesday evening

One of the District’s coolest art spaces will be open to the public Wednesday evening for a free open house. Dupont Underground, the nonprofit that manages the former site of 20th-century streetcar tunnels and platforms beneath Dupont Circle, says its 15,000 square feet of converted space will feature various performances and exhibitions between 6 p.m. and 8 p.m.

“We’ll be highlighting the best of DU in order to make it clear how important this community is to this city,” the group explains. The site, which also once served as a fallout shelter in the late 1960s and reopened in 2016, is accessible by way of stairwells just off the circle. Among the artists and organizations slated for Wednesday are Uncalled 4 Band, World Press Photo, the Choral Arts Society of Washington, and DC in Motion, representing a range of art forms.

The space is known for previously staging pop-up exhibits like “Raise/Raze,” a repurposing of more than 650,000 white plastic balls earlier featured in the National Building Museum’s 2015 “Beach” installation. In addition, Dupont Underground regularly has photo projections.
