Petra was built around a desert water system

The Nabataeans carved a capital into sandstone and channelled flash floods through it The Nabataean kingdom grew rich on incense and spice caravans passing through its capital, Petra, in what is now Jordan. From about the first century BCE its engineers cut cisterns, channels and terracotta pipes into the rock to capture winter storms. Rome absorbed the kingdom in 106 CE, and the city slowly emptied. It sits in Mondo's history collection, one of 200 facts that each trace back to the reference below.
