Conservation & restoration

Examining and conserving paintings from six centuries

Our conservation and restoration workshop in Zurich is equipped with the latest technology for dating artworks and establishing their authorship, for planning conservation or restoration work, or simply for satisfying academic curiosity. Tried-and-tested art technological examination methods range from inspecting the surface of an object under a stereo microscope to creating and evaluating technical photographs – which can sometimes reveal surprising information.
