THNOC’s interpretative displays are located in the beautiful courtyards of the historic Merieult House at 533 Royal Street; the former residence of the institution’s founders at 718 and 722 Toulouse Street; and the Seignouret-Brulatour Building at 520 Royal Street. Each courtyard explores different aspects of history, including the construction and architecture of the various sites; the lives of each building’s occupants, including free and enslaved people; notable events; and the later efforts of preservationists who have restored the properties to their current condition.
