Seven Smithsonian sites in Washington, DC, were closed on August 6 after a mechanical issue interrupted the buildings' cooling system.
The affected locations are the National Museum of the American Indian, Hirshhorn Museum, National Museum of Asian Art, National Museum of African Art, Smithsonian Castle, Arts and Industries Building, and the S. Dillon Ripley Center.
According to the Smithsonian, the buildings stopped receiving cold water from the system that helps regulate indoor climate. The timing comes during an intense summer stretch in the capital, where temperatures have been climbing near 100 degrees Fahrenheit.
The situation echoes a similar disruption last summer, when several Smithsonian venues temporarily paused public access because of central plant issues affecting heating, ventilation, and air conditioning. In that case, the museums reopened after a few days.
For now, there is no confirmed reopening schedule. The Smithsonian says updates will be shared through its visitor information channels as repairs move forward. This kind of infrastructure response highlights how advanced climate control remains essential to preserving cultural spaces in a warming future.
