About Us

Our mission is to protect the unique architectural heritage of our region and promote preservation and planning practices that foster healthy, livable, and sustainable communities.

Who we are: The Landmark Society of Western New York, Inc., is one of the oldest and most active preservation organizations in America. It is a not-for-profit membership organization dedicated to preserving, interpreting and fostering interest in the architectural, historical and cultural heritage of our region. The Landmark Society's service area covers nine Western New York counties.

Our history: Landmark was organized in 1937, preceding by ten years the founding of the National Trust for Historic Preservation, of which it is a charter member. Helen Ellwanger led a group of volunteers in founding an organization to protect and preserve the Campbell-Whittlesey mansion. Built on this modest foundation, The Landmark Society has grown into a museum and preservation organization with a state and national reputation.
