The National Sites and Monuments Service (Service des sites et monuments nationaux – SSMN) is an administration under the direction of the Ministry of Culture, Higher Education and Research (Ministère de la Culture, de l'Enseignement supérieur et de la Recherche). Its main objectives are to:
- study and showcase national architectural heritage;
- protect and regularly maintain classified historical sites;
- oversee the completion of measures and work to repair and restore classified sites and buildings (e.g. Government subsidy to restore buildings constructed prior to 1914);
- coordinate and oversee public initiatives on restoration of national architectural heritage.
