Petra (Arabic: البترا, 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 BC as the capital city of the Nabataeans, it is a symbol of Jordan, as well as Jordan's 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". Petra was named amongst the New7Wonders of the World in 2007 and was also chosen by the Smithsonian Magazine as one of the "28 Places to See Before You Die".
Threats to Petra:
The site suffers from a host of threats, including collapse of ancient structures, erosion due to flooding and improper rainwater drainage, weathering from salt upwelling, improper restoration of ancient structures, and unsustainable tourism. The last has increased substantially, especially since the site received widespread media coverage in 2007 during the New Seven Wonders of the World Internet and cell phone campaign.
In an attempt to reduce the impact of these threats, Petra National Trust (PNT) was established in 1989. Over this time, it has worked together with numerous local and international organizations on projects that promote the protection, conservation and preservation of the Petra site. Moreover, UNESCO and ICOMOS recently collaborated to publish their first book on human and natural threats to these sensitive World Heritage sites. They chose Petra as its first, and the most important example of threatened landscapes. A book released in 2012, Tourism and Archaeological Heritage Management at Petra: Driver to Development or Destruction?, was the first in a series of important books to address the very nature of these deteriorating buildings, cities, sites, and regions. The next books in the series of deteriorating UNESCO World Heritage Sites will include Macchu Picchu, Angkor Wat, and Pompeii.
