Frederick Law Olmsted National Historic Site

Established in 1979, transcends the traditional role of a historic house museum by also serving as a center for the study and preservation of American landscapes.

This mission is being accomplished through the combined efforts of the Olmsted Archives, the Landscape Education Program and the Olmsted Center for Landscape Preservation. Together these programs enhance appreciation and stewardship of America’s most valued public spaces
