Abstract

In the present paper the “Three R” Strategy for archaeological consolidation is described, referring to some well-known historical examples and then to some significant cases on UNESCO sites performed by the author. The problem of conserving the constructive info of ancient structures along centuries is summarized, together with a set of recurrent structural problems. Three case studies of sites are explained, two located in Arabic Peninsula (Dhofar district, Sumhuram– Al Balid), one in Jordan (Petra district – Shawbak). The replacement of walls (with or without mortar joints) is performed, together with the strategy to assess a respectful, recognizable and reversible consolidation technique.
