The area before you is known traditionally as Bab El-Siq ('Gate to the Siq' in Arabic), so-named by Petra's Bedouin inhabitants. This area contains several rock-hewn monuments and memorials, including the distinctive tower tombs, known as the Djinn Blocks, the rock-cut funerary complex of the ‘Obelisk tomb’ and the 'Bab El-Siq Triclinium'. This area traces a path that follows the course of the Wadi Musa (in Arabic ‘Valley of Moses'), the meandering riverbed that flows from Ain Musa (Spring of Moses) into Petra, The Bedouin believe Ain Musa is the spring that gushed forth when Moses smote a rock in Biblical times, The valley was formed as a result of floodwater erosion and the Nabataeans carved water cisterns and channels to divert the water and channel it into Petra for their use. TheBab El-Siq terminates at the start of the chasm of the Siq
