The Nabataeans were masters of hydrology and manipulated rain run-off and underground aquifers to thrive in this desert landscape. This great well was one of over 60 wells currently known in the city. The wall supports – added in the 20th century – were built from railway sleepers pilfered from the Hejaz Railway. The Al Mahajar tombs are especially photogenic and some of the oldest at Madain Saleh.
