Petra, an archaeological site in Jordan's southwestern desert, dates back to around 300 B.C. It was the capital of the Nabatean Kingdom and is renowned for its rock-cut architecture and water conduit system. Petra is often referred to as the 'Rose City' due to the color of the stone from which it is carved. The city is accessed via a narrow canyon called Al Siq, which leads directly to the iconic Treasury (Al Khazneh), a majestic temple with a Greek-style facade. The site features numerous other structures, including tombs, temples, a theatre, and the Monastery (Ad Deir). Petra has earned UNESCO World Heritage status and was listed as one of the New Seven Wonders of the World. Its vast historical significance and well-preserved monuments make it a valuable cultural treasure and a fascinating ancient city that reflects the ingenuity of its constructors.
