The Stylite Tower is part of the UNESCO archaeological site of Umm ar−Rasas (Jordan). It represents a unicum in its category and has a fundamental value for the Jordanian Cultural Heritage as a symbol and an emblem of Jordan’s history and culture. The monument has evident signs of deterioration that appear in the form of substantial detachments of the plaster, water infiltration, erosion and fractures. Given the need to preserve this important ancient monument and for public safety reasons, a high−detail analysis of the Tower has been achieved through the realization of 3D geometrical surveys (Photogrammetry and Laser Scanner) and non−invasive geophysical surveys (using Ground Penetrating Radar Technique). The use of non−destructive testing techniques has provided encouraging results for the struc− tural planning of diagnostic, consolidation and restoration activities.
