The municipalities, through their general development plans (PAG), must identify and protect buildings of local interest. In order to establish a coherent and consistent protection for all the built heritage, including that which is of particular importance at the communal and local level, the identification of the built heritage worthy of protection has been carried out for the whole of the Grand Duchy, together with the communes, their engineering offices and the National Institute for Architectural Heritage – INPA (formerly the Service des sites et monuments nationaux). In parallel to this vast analysis and the communal protections that follow, the State, through the INPA, has been able to significantly expand the list of objects benefiting from national protection and begin the scientific inventory of built heritage.
Buildings and objects with national protection
For the restoration of protected heritage, namely buildings classified as national cultural heritage or located in a protected area of national interest, the experts of INPA must be requested. At best, INPA’s advice is given at the beginning of the planning of the work.
The buildings classified as national cultural heritage cannot be modified without the authorization of the Minister of Culture. Projects that require modifications by the owners are reviewed by the national INPA and the Cultural Heritage Commission (COPAC), which advise the Minister.
During the works, the owners, their architects and tradesmen are accompanied by INPA experts.
Financial assistance of up to 50% of eligible costs may be granted for the restoration of protected buildings.
