Arts and Industries Building
The Arts and Industries Building (AIB) is the second oldest of the Smithsonian museums on the National Mall in Washington, D.C. Built between April 1879 and March 1881. It is the Nation’s best-preserved example of nineteenth century world’s fair or exposition architecture. Restoration of the exterior–replacement of the roof and windows and upgrades to the building’s structure–began on November 15, 2010, and was completed in 2015.
The building is currently closed to the public.
