Conservation balances measurement with craft. Teams deploy laser scanning, photogrammetry, and material sampling to understand weathering, then apply discreet repairs that respect patina.


🧰 Methods

  • Crack mapping guided by digital models.
  • Mortar compatibility ensures breathable joints.
  • Iron cramps: monitored and replaced when necessary.

🎨 Patina Philosophy

  • Keep history visible, avoid over-cleaning.
  • Respect color variation and tool marks.
  • Make interventions legible yet unobtrusive.

Conservation is a slow conversation with stone.
