Here’s to 50! This year marks 50 years since the establishment of the National Historic Preservation Act. Preservation Oklahoma’s traveling exhibition, “Preservation50: Oklahoma Celebrates the National Historic Preservation Act,” highlights this monument and examines the Act’s impact on the state of Oklahoma.

President Lyndon B. Johnson signed the National Historic Preservation Act into law in 1966, establishing the structure and mechanisms for treatment of the nation’s archeological and historic properties. The Act facilitated the creation of the National Register of Historic Places and State Historic Preservation Offices. The Oklahoma Historical Society, in conjunction with the State Historic Preservation Office, partner agencies and organizations, is participating in Preservation50, the national celebration of the Act’s 50th anniversary. During the exhibit, visitors experience photos of buildings and structures listed on the National Register of Historic Places and learn more about why the Act is important to preserving Oklahoma’s historic resources. The exhibit is free of charge courtesy of the State Historic Preservation Office.
