Prof. JoAnn Cassar and Roberta De Angelis – University of Malta Educational Linkage Approach In Cultural Heritage Abstract Just like detectives who look for clues to solve a crime, a team of experts (conservators, scientists, architects, art historians, archaeologists, engineers, etc.) work together to investigate the problems of heritage sites. The main objective of this investigative process is to try to get to the origin of the problem/s (i.e. the causes of deterioration), so that this/these can be removed or at least reduced before intervening directly on the heritage site. Addressing the causes of deterioration before “touching”the building, cleaning it or repairing its damage is the most efficient way of ensuring the long-term preservation of any heritage site.
