When you walk around places like Waterford, you can feel the history of the place. That is not an accident. The care and protection of historic areas like Waterford is largely defined as historic preservation. But, preservation can take almost as many forms as there are historic buildings in the United States.
Historic preservation is largely agreed to be defined as the interpretation, care of, and protection of historic artifacts and objects, sites, buildings and structures, and districts. There are multiple different fields of preservation (that often intersect with other fields and interests) in which people dive into that definition: including archaeology, architecture, museums, planning, building technology, advocacy, material culture, conservation, public history, and more. What the definition of historic preservation means and how they interpret it in their work can differ from preservationist to preservationist.
So, what does historic preservation mean to preservationists in Loudoun County? Below learn a little bit about the insights of what preservation means to them from Margaret “Margie” Salazar-Porzio, Ph.D. of Oatlands Historic House and Gardens, Ian MacDougall of the Virginia Piedmont Heritage Area, William Milone of Loudoun County Planning and Zoning, Jana Shafagoj of Morven Park, and Abigail “Abby” Zurfluh of the Waterford Foundation.
Margaret “Margie” Salazar-Porzio, Ph.D. is the Executive Director of Oatlands, a site of the National Trust for Historic Preservation in Loudoun County. With more than 15 years of experience in museums and public humanities, she previously served in leadership roles at the Smithsonian Institution, the Institute of Museum and Library Services, and the President’s Committee on the Arts and the Humanities. At Oatlands, she is leading a community-centered transformation focused on descendant engagement, education, land stewardship, and long-term sustainability.
What does historic preservation mean to you?
“To me, historic preservation is about stewarding places in ways that protect their historical and cultural significance while also inviting active engagement, inquiry, and connection to the present. Preservation to me is about honoring the people and their lives that are embedded in a landscape, including those that are difficult or complicated. At Oatlands, preservation means holding complexity, centering descendant voices, and ensuring that the site remains relevant and meaningful to the communities it serves today and in the future. As stewards, we must treat the site as a shared inheritance that extends beyond any one generation. Our choices today must therefore be guided by the long view, made with the understanding that others will inherit this place and continue its care.”
How did you get interested in historic preservation?
My path into historic preservation came through public history and museum work. I’ve spent my career thinking about how history is interpreted, who gets to tell those stories, and how institutions can better reflect the full American story. Working at places like the Smithsonian and now at Oatlands has deepened my belief in the power of place: that historic sites are not simply lovely backdrops; they are places where civic learning, dialogue, and connection can unfold. With thoughtful interpretation, these places draw people into history as a lived experience, encouraging reflection and honest engagement with our shared past.
