The Smithsonian has filed an application with the D.C. Historic Preservation Board requesting Historic Landmark status for the Hirshhorn Museum and Sculpture Garden. Buildings are generally not considered historic until they are more than 50 years old, but the Smithsonian is filing the application for the Hirshhorn under Criteria G, which allows a newer building to qualify if it “embodies the distinctive characteristics of a type, period, or method of construction.”

Smithsonian historic preservation specialist Carly Bond says the Hirshhorn is a unique representation of post-war Modernist architecture.
