Sister cities of Petra

Petra (Arabic: البتراء, Al-Batrāʾ, Ancient Greek Πέτρα) is a historical and archaeological city in the southern Jordanian governorate of Ma'an, that is famous for its rock-cut architecture and water conduit system. Another name for Petra is the Rose City due to the color of the stone out of which it is carved.

Established possibly as early as 312 BCE as the capital city of the Nabataeans, it is a symbol of Jordan, as well as its most-visited tourist attraction. It lies on the slope of Jebel al-Madhbah (identified by some as the biblical Mount Hor) in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. Petra has been a UNESCO World Heritage Site since 1985.

The site remained unknown to the Western world until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt. It was described as "a rose-red city half as old as time" in a Newdigate Prize-winning poem by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage". See: UNESCO Intangible Cultural Heritage Lists. Petra was chosen by the Smithsonian Magazine as one of the "28 Places to See Before You Die."
