Wadi Rum (Arabic: وادي رم) also known as The Valley of the Moon (Arabic: وادي القمر) is a valley cut into the sandstone and granite rock in southern Jordan 60 km (37 mi) to the east of Aqaba; it is the largest wadi in Jordan.[1]Wadi Rum is Arabic for “Roman Valley”, or “Valley of the Romioi” (Ρωμιοί), as the Greeks were also called in the early Byzantine era by Arab people, probably referring to Christian Byzantine monastic or ascetic communities in the area, for which they were also known as “monks of the desert”, before the expansion of the Rashidun Caliphate.
Many Movies have been filmed in Wadi Rum such as the famous “Lawrence of Arabia”, “Transformers”, “Red Plant”, and more recently, “The Martian”.
Wadi Rum has been inhabited by many human cultures since prehistoric times, with many cultures–including the Nabateans–leaving their mark in the form of rock paintings, graffiti, and temples.
In the West, Wadi Rum may be best known for its connection with British officer T. E. Lawrence, who passed through several times during the Arab Revolt of 1917–18.[2] In the 1980s one of the rock formations in Wadi Rum was named “The Seven Pillars of Wisdom” after Lawrence’s book penned in the aftermath of the war, though the ‘Seven Pillars’ referred to in the book have no connection with Rum.
