How could the people of Petra carve such magnificent structures into the high rock walls? No one can answer this question today. The Nabateans left few written records of their history and culture. If there were more evidence now, the mysteries and secrets of Petra might be solved.
In AD 106, Roman soldiers took over Petra. Gradually, new trade routes that did not pass through Petra were developed. The city where 20,000 people lived at its peak was beginning to decline.
Worse still, a series of earthquakes damaged much of the city. Eventually, Petra was abandoned, forgotten, and lost to Western history. However, a few Arab tribes continued to use the ruins of the city as a sanctuary and kept its location a close secret.
