Petra, meaning stone, is famous for its rock-cut architecture and water conduit system and has been a UNESCO World Heritage Site since 1985. Established possibly as early as 312 BC, it lies on the slope of Mount Hor in a basin among the mountains, the valley running from the Dead Sea to the Gulf of Aqaba. Unknown to the Western world until 1812, It was described as "a rose-red city half as old as time". The Smithsonian Magazine chose Petra as one of the "28 Places to See Before You Die". According to Arab tradition, Petra is the spot where Moses struck a rock with his staff and water came forth. Petra is also featured in films such as Arabian Nights, Passion in the Desert, Mortal Combat, Sinbad and the Eye of the Tiger, Transformers: Revenge of the Fallen and famously Indiana jones and the Last Crusade.
