Petra (Arabic: البتراء, Al-Batrāʾ; Ancient Greek: Πέτρα), originally known to the Nabataeans as Raqmu, is a historical and archaeological city in southern Jordan. The city 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. Petra is one of the New7Wonders of the World.
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".
