In a city known for its architecture, culture and history — and the use of these treasured elements in tourism promotion — it can be a surprise when they are neglected by the city that originated or inspired them. While the Louisiana Landmarks Society can’t solve all of the problems, for the past 71 years, the group has shone a light on at-risk historic buildings and other structures, such as tombs, in danger of falling down and being demolished by neglect and on neighborhoods that are at risk of being permanently altered by destructive new developments. In 2005, the organization annually began a program naming “New Orleans Nine Most Endangered Sites” to bring awareness to the issues these programs or historic structures face.
