Conservation and preservation

The  Archaeological Survey of India (ASI), as an attached office under the Department of Culture, Ministry of Tourism and Culture, is the premier organization for the archaeological researches and protection of the cultural heritage of the nation. Maintenance of ancient monuments and archaeological sites and remains of national importance is the prime concern of the ASI. Besides it regulate all archaeological activities in the country as per the provisions of the Ancient Monuments and Archaeological Sites and Remains Act, 1958. It also regulates Antiquities and Art Treasure Act, 1972. For the maintenance of ancient monuments and archaeological sites and remains of national importance the entire country is divided into 24 Circles. The organization has a large work force of trained archaeologists, conservators, epigraphist, architects and scientists for conducting archaeological research projects through its Excavation Branches, Prehistory Branch, Epigraphy Branches, Science Branch, Horticulture Branch, Building Survey Project, Temple Survey Projects and Underwater Archaeology Wing.

The real challenge before us is to plan the necessary measures of conservation with a view to assure the survival of these built cultural heritage and unique symbols of our civilizations for centuries to come, with as little intervention as possible but without altering or modifying in any way the authenticity of their original character. To ensure the stability as well as proper conservation of our cultural heritage, there is a need to give more thrust to the scientific research in conservation options must be based on a preliminary investigation which includes the knowledge of physical nature of the object (constituent materials, architectural characteristics, production techniques, state of decay) and of the factors which induce or could induced its decay. In other words, as in the case of medical study the field of conservation therapy to be based on a correct diagnosis.

The role of scientific discipline is vital to both these steps of conservation activities. Accordingly, a specific objective of scientific research activities in conservation being carried out by the Science Branch is aimed to study:

  • Material deterioration process.
  • Basic studies of intervention technologies.
  • Basic studies on materials.
  • Diagnostic technologies.

The main activities of Science Branch are:

  • Chemical treatment and preservation of about 5000 centrally protected monuments including 18 world heritage monuments.
  • Chemical treatment and preservation of museum exhibits and excavated objects
    Scientific and technical studies as well as research on material heritage of different building materials to study the causes of deterioration with a view to evolve appropriate conservation measures in order to improve the state of preservation of our built cultural heritage and physical heritage as well.
  • Chemical conservation of monuments and heritage sites abroad.
  • Technical assistance to state protected monuments as well as built cultural heritage under the control of trusts in the form of deposit works.
  • To impart training on chemical conservation to the students of Post Graduated Diploma in Archaeology, from Institute of Archaeology, New Delhi.
  • To organize awareness programme and workshops /seminars with regard to scientific conservation works
