The Siq6. T-Shirt

The Siq literally ‘the Shaft’) is the main entrance to the ancient city of Petra. The dim, narrow gorge (in some points no more than 3 m wide) winds its way approximately 1.2 km and ends at Petra's most elaborate ruin, Al Khazneh (the Treasury). Unlike slot canyons like Antelope Canyon, which are directly shaped by water, the Siq is a natural geological fault split apart by tectonic forces; only later was it worn smooth by water. The walls that enclose the Siq stand between 91–182 m in height. The Siq was used as the grand caravan entrance into Petra. Along both walls of the fissure are a number of votive niches containing baetyli, which suggest that the Siq was sacred to the Nabatean people.
