Petra, Jordan’s most famous archaeological site, is an ancient city carved into vibrant sandstone cliffs. Once a thriving Nabataean trade hub in the 4th century BC, it remains a UNESCO World Heritage Site and one of the New Seven Wonders of the World. Visitors enter through the Siq, a narrow canyon leading to Al-Khazneh (The Treasury), Petra’s most iconic structure. Highlights include the Monastery (Ad-Deir), the Royal Tombs, and the Great Temple. Best visited at sunrise or sunset, Petra’s rose-red hues and intricate carvings make it a must-see destination.
