Three Hours Drive South from Amman is the most famous attraction in the kingdom, Petra which was a fortress city , literally carved out of craggy rocks, by the Nabataeans 800 B.C..
Fortified behind a narrow deep siq (gorge) that slowly winds through a massive rock wall. It is a wading, one kilometer long fissure between the overhanging clefts that seem to meet 300 feet overhead. Within Petra you will see soaring temples, royal tombs, Roman theatre, water channels, arched gates and others. Petra was discovered when a Swiss explorer disguised as ab Arab, fell on it in 1812
