About the National Park Service
In 1966, the National Historic Preservation Act was passed to preserve historical and archaeological sites in the United States. The act created the National Register of Historic Places, the list of National Historic Landmarks, and the State Historic Preservation Offices, all of which are administered by the National Park Service. The National Park Service website offers detailed information on Federal tax incentives for historic preservation, technical preservation services, the Secretary of the Interior's Standards for Preservation, Rehabilitation, Restoration, and Reconstruction as well as National Register listings and nationwide preservation resources.
About the National Trust for Historic Preservation
The National Trust for Historic Preservation supports the preservation of America’s diverse historic buildings, neighborhoods, and heritage through programs, resources, and advocacy. Through the organization’s National Treasures program, they advocate for the preservation of historic places by raising funds, building coalitions to prevent demolition, fighting the courts to save sites from deterioration, and making sure that the icons of the past remain with us in the future. The National Trust also owns and operates a diverse collection of 27 sites across the country that are open to the public. Their site offers information on a variety of programs, tours, and ways to get involved in your community.
