La conservación de las pinturas murales del Camposanto de Pisa"

The recovery, restoration and relocation of the medieval frescoes of the Monumental Camposanto of Pisa took a long time: "Three days to destroy them, more than seventy years to bring them back to life" are the lapidary words of the Director of Restoration Works Antonio Paolucci. In 1944, a US bombing by mistake completely lit the ceiling of the Cemetery destroying or damaging the 2500 square meters of frescoes. After the first emergency work for the "strappo" of the frescoes most exposed to rain, the reconstruction of the ceiling and the "strappo" of the remaining frescoes, were carried out very slowly, which remained in the warehouse until 2005. From that year on, the project for the relocation of the frescoes to their original position. The frescoes are now protected from condensation of atmospheric water vapor and the deposition of fine particles. The system is innovative and invisible to the visitor and is continuously controlled remotely by a network of microclimatic sensors that anticipate and program the heating of the surface of the frescoes near the conditions of dew formation.
