The Louisiana Landmarks Society is a non-profit 501(C)3 preservation advocacy organization, established in 1950. With founders such as Samuel Wilson, Jr. and Martha Robinson, Landmarks rapidly defined preservation advocacy in New Orleans by leading the charge to preserve Gallier Hall in 1950 and defeat the proposed Riverfront Expressway a decade later. Today, the spirit of the organization’s founders lives on in Landmarks’ annual “New Orleans’ 9 Most Endangered” listing of at-risk historic properties. Landmarks’ preservation activities restored the c. 1799 Pitot House to its Creole West Indies colonial charm and current use as a site for preservation education.
Focusing their efforts to the New Orleans area, Landmarks' mission is to promote historic preservation through education, advocacy and operation of the Pitot House.
