Wadu Rum - rupestral engravings

In Wadi-Rum, it is the wind that throughout the millennia has eroded the rocks, thus creating the picturesque landscapes with reddish sands. Already inhabited in prehistoric times; as witnessed by the finds of stone tools dating to the Paleolithic and Neolithic periods , this great valley was roamed for millennia by hunters and nomads, who left interesting traces of their passage .Most of these are graffiti , rupestral engravings both on the rocks and rock walls and inside natural caves , presumably ranging in time from the 4th millennium BC up almost to the present .
