The Cathedral of Noto, built in the eighteenth century, and damaged by an earthquake occurred in 1990 collapsed partially the evening of March 13, 1996. The removal of the collapsed parts had to be carried out following a methodology which did not have any existing guideline. After the provisional structures were built for the safety of the site, the survey of the site was carried out by traditional geodetic techniques and by an aereal photogrammetry of the ruins. Every recoverable block and piece of material was cleaned, catalogued and removed carefully following a stratigraphic methodology. All the materials are preserved in a special site, protected from rain and damages and will be reused in the reconstruction of the Cathedral. The design for reconstruction will then be based a good knowledge of the remains. The special methodology followed and the survey of the remains will be presented.
