As part of a work of maximum urgency a corner of the attic on the Turati Street was rebuilt, which had considerable collapses.The intervention was performed partly for anastylosis by reconstructing the part of the masonry damaged by the same original blocks with “sew and unsew consolidation technique”, after injection of mortar compatible with the results of the investigations on the original materials; partly with the replacement with new calcarenite elements.
