The name of the famous ancient city in Petra, Jordan, is Petra itself. Known as "the Rose City" due to the color of the sandstone from which it is carved, Petra was the capital of the Nabataean Kingdom in the 4th century BC and prospered as a center for trade. Its remarkable architecture, including the iconic Al-Khazneh (The Treasury) carved into the rock face, showcases the ingenuity of its builders. Today, Petra is a UNESCO World Heritage Site and attracts visitors from around the globe, highlighting its historical and cultural significance.
