Pennsylvania Avenue Redevelopment, 1965

Previous | Home | Next


The first plans for upgrading Pennsylvania Avenue proposed a “Northern Triangle” of government and private office buildings punctuated by two large plazas. The square stretching between 14th and 15th Streets, NW would have required the demolition of three historic buildings, including the Old Post Office. Despite presidential support for this plan, growing support for historic preservation led to challenge of the plan’s ambitious redevelopment aims. In 1965, Pennsylvania Avenue between 3rd and 15th Streets, NW became a National Historic Site, and in 1971, citizen action coalesced around the successful “Don’t Tear It Down” movement to save the Old Post Office.
