Gen. Kemper and Leila Williams, the founders of The Historic New Orleans Collection, were committed to preserving the French Quarter's unique structures. Carrying on their preservationist mission, THNOC has continued to restore significant Vieux Carré buildings and maintain them for future generations. In their varied origins and plans, the buildings that house The Collection’s galleries and research center reflect several eras of New Orleans architecture.

The Historic New Orleans Collection was originally housed in this building, which is temporarily closed for renovation. 


Chartres Street Campus

The Williams Research Center, the Boyd Cruise Gallery, the Laura Simon Nelson Galleries for Louisiana Art, and administrative offices are located on Chartres Street.

The Historic New Orleans Collection expanded its operations to a third campus in the French Quarter in spring 2019. 


To address damage sustained in Hurricane Ida in August 2021, The Historic New Orleans Collection was honored to receive funding from a 2021 Disaster Mitigation grant provided by the National Endowment for the Humanities (NEH) and administered by the Louisiana Endowment for the Humanities (LEH).
