CESI monitoring system of Leonardo’s Last Supper

​Structural monitoring system of the Leonardo’s ‘’Last supper’’ wall – Refectory of Santa Maria delle Grazie – Milan, Italy

25 Jan 2012, 19 and 20 May 2012, earthquakes measuring from 4.9 to 5.9 magnitude (Richter scale) shook Northern Italy from Turin to Venice and particularly Milan.

The Automatic Monitoring System (AMS) of Leonardo’s ‘’The Last Supper’’ allowed the Superintendent for the Architectural and Landscape Heritage of Milan to exclude for certain that the masterpiece has been damaged by the seismic event.

The AMS, installed by CESI in its first configuration during 1981, allows the continuous monitoring of the wall’s static behavior as a function of time and boundary conditions, including the two side walls and the vaulted ceiling of the Refectory of Santa Maria delle Grazie.
The AMS consists of a data-logger, for the acquisition of the transducers, connected to the remote Control Centre with the specific software “INDACO®” (owned by CESI) for data transmission, processing, visualization and storage.
