Il rilievo digitale per la documentazione morfologica: diagnostica e recupero del complesso monumentale di Al-Jazzar ad Acri, Israele

The study of Al-Jazzar white mosque, in San Giovanni of Acre in Israel (UNESCO world heritage since 2001), concerned the documentation of the conservation status, conducted through digital technologies, of the monumental complex. The survey campaign, conducted in 2017, has produced a survey of the entire monument, considered today the second Muslim religious complex, in terms of size and importance, in Holy Land. The aim of the research is the realization of drawings and models capable of transmitting the historical and material value of the different environments and construction apparatus, developing reading systems for diagnostic analyses on the state of conservation. The survey has made possible to propose useful considerations to decipher signs and masonry stratifications also related to elements and materials of reuse, such as the columns from nearby Roman sites and Crusader cisterns. The project, responsible prof. S. Parrinello, is governed by an agreement with DICAr Department of Civil Engineering and Architecture of University of Pavia for the application of survey methodologies functional to the creation of a three-dimensional database for the documentation of the site, usable as a knowledge base for the development and archiving of structural and conservative diagnostic observations. The research highlights the potential of digital survey to plan recovery interventions and define guidelines for consolidation, functional rehabilitation and enhancement of historic environments in Al-Jazzar complex.
