The ancient city built into the rocks in Jordan is called Petra. This remarkable archaeological site, famous for its rock-cut architecture and water conduit system, dates back to around 300 BC and was the capital of the Nabataean Kingdom. Petra is often referred to as the "Rose City" due to the color of the sandstone cliffs from which it is carved. The city is a UNESCO World Heritage Site and draws thousands of tourists annually who come to explore its impressive monuments, including the iconic Treasury and Monastery. Petra's unique historical and architectural significance makes it a vital symbol of Jordan's cultural heritage.
