“Preservation 50” focuses on the National Historic Preservation Act’s impact on Oklahoma and explores the resulting conservation efforts of our state’s historical landmarks. 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. “Oklahoma’s Most Endangered Historic Places 2017” brings the issues of the neglected historical or architectural properties and sites in Oklahoma to light. Across the state many sites have succumbed to deterioration after years of disregard, poor maintenance, insufficient funding or other causes. The exhibit reflects the history of Oklahoma by acknowledging the citizens who crafted and inhabited these historical places. Both traveling exhibits were created by Preservation Oklahoma, the only private, nonprofit membership organization that is dedicated to historic preservation activities in Oklahoma.
