Known as the ‘Red Rose’ city, Petra is undoubtedly one of the wonders of the ancient world. Notably accessed on foot by way of the winding and narrow Siq Canyon, the first glimpse of the glistening façade of the ochre-hued Treasury is memorably impressive. Although a settlement since pre-history, Petra was the capital of the Nabatean Kingdom and fell under the control of the Roman Empire at the beginning of the 2nd century. Rich in natural resources, practically impregnable, and at the crossroads of the region’s most important trade routes, the city amassed great wealth. Today the evocative remains of temples and tombs, monumental public buildings, and huge theatres retain much of their scale and grandeur.
