Protecting the archaeological heritage from structural risks: some significant cases.

A novel 'Three R' strategy for archaeological consolidation is introduced, focusing on the preservation of ancient structures while addressing structural risks. This approach emphasizes respectful, recognizable, and reversible techniques to maintain the constructive information of historical sites over centuries. The study highlights three significant case studies: two in the Dhofar district (Sumhuram–Al Balid) and one in Jordan's Petra district (Shawbak). By replacing walls with or without mortar joints, researchers demonstrate a method to mitigate recurrent structural problems while ensuring minimal intervention that remains reversible and culturally sensitive. This strategy offers a practical solution for conserving UNESCO World Heritage Sites, balancing technical precision with ethical considerations.
