What can you find in our intervention files?

  • About 20,000 files, the scientific archive of the Institute.
  • A unique collection on the study, conservation and restoration of Belgian art heritage.
  • All documentation prepared by restorers, art historians and chemists during the study, treatment or laboratory analysis of an artwork.
  • Technical photographs (UV, IR, during treatment...).

The files are on the priority list of documents digitised by our teams in collaboration with the DIGIT unit.
