Behind the Great Temple, Petra
The road from Qasr al-Bint to the High Place runs eastward behind the Great Temple (map) and past this lone, standing column, which is part of an unexcavated (2005) building. The column is also known as "Pharaoh's Shaft" (pun intended). It is viewed here from the south.
References to Pharaoh and Moses are part of the local folklore, which holds (impossibly) that Pharaoh pursued the Israelites from Egypt to Petra after the parting of the Red Sea.
