Preservation Is Our Mission

As the leading research, technology and training center within the National Park Service, we help preservationists find better tools, materials, and approaches to conserving buildings, landscapes, sites, and collections. We conduct research and testing in our own laboratories. Our staff provides cutting edge training and supports research and training projects at universities and nonprofits around the U.S. We push the envelope of current preservation practices by exploring advances in science and technology in other fields, applying them to issues in cultural resources management. Discover a community where you can preserve America’s material culture.
