There are three theaters in Petra. The most impressive one is the Main Theatre. It was carved into the side of a cliff called Jabal Al-Madbah at the base of the High Place of Sacrifice. This auditorium was commissioned by Nabataean King Aretas IV (9 BC – 40 AD). He was known as the “Friend of His People.” The 2,000 foot stadium accommodated 4,000 spectators.
