The Nabatean culture erected the city to highlight solstices, equinoxes. An ancient civilization built the famous, stone-hewn city of Petra so that the sun would illuminate their sacred places like celestial spotlights, a new study says.

What was Petra used for?

Petra began as a main stopping point for Nabataean and foreign traders. These nomadic merchants carried textiles, incense, spices, ivory, and other precious goods grown or manufactured in Arabia, Asia, and Africa. As the trade market grew, so did Petra.

Why is Petra so important?

The site is considered significant by historians and archeologists alike because of its beautiful rock-cut architecture and innovative water management system, the latter of which made the region inhabitable, given that it is surrounded by desert and rugged, mountainous terrain.
