The Smithsonian Arts and Industries Building is a museum building in Washington, D.C., built in 1881 to house the United States National Museum. The building was the first structure built specifically to serve as a national museum, and it was designed to showcase a wide range of objects and artifacts related to art, science, and industry. The building was closed to the public in 2004, but it is currently undergoing renovations and is scheduled to reopen in 2024. When it reopens, the building will serve as a space for exhibitions, public programs, and other cultural events.
