Since 1993, the ''Commune urbaine d'Antananarivo'' (CUA) has increasingly sought to protect and restore the city's architectural and cultural heritage. In 2005, CUA authorities partnered with the city planners of the Île-de-France to develop the ''Plan VertPlan Bleu'' strategy for creating a classification system for ''Zones de Protection du Patrimoine Architectural, Urbain et Paysager'', areas of the city benefiting from legal protection and financial support for their historic and cultural heritage. The plan, which is being implemented by the ''Institut des Métiers de la Ville'', prevents the destruction of historic buildings and other structures, and establishes construction codes that ensure new structures follow historic aesthetics. It also provides for awareness raising campaigns in favor of historic preservation and undertakes projects to restore dilapidated historic buildings and sites. Under this plan, 19th-century sites, like the Ambatondrafandrana tribunal and the second residence of Rainilaiarivony, have been renovated.
