UNESCO Expert Mission, Petra, April 2009
Wednesday, 1 April 2009
World Heritage Properties
Since the crack was detected in March 2009, three missions were undertaken by a UNESCO expert (April, June, and August 2009). These expert missions determined that the rock is in an extremely unstable condition and poses a very serious threat to visitor safety, as it is located in the Siq which is the only entrance path into the site. The UNESCO expert, together with a local expert, prepared the terms of reference for the different stages of works required and also conducted a first visual geological risk assessment of the Siq.
