Madain Saleh is an outstanding example of the Nabataeans architectural accomplishment and hydraulic expertise.
Madin Saleh reached its peak as the major staging post on the main northsouth trade route.
Thus, Hegra as a center of trade began to decline, leading to its abandonment and disuse.
However, Hegra did served as a station along the religious route, providing supplies and water for pilgrims.
The Nabatean kingdom was not just situated at the crossroad of trade but also of culture.
In contrast to the elaborate exteriors, the interiors of the rock-cut structures are severe and plain.
Madain Saleh is officially protected as an archaeological site since 1972, for its tourism potential.
