How did nabataeans build petra?

The Nabataeans carved Petra's iconic rock-cut architecture by hand using chisels, hammers, and picks. They were skilled in manipulating the rock's natural layers and avoiding structural weaknesses, creating intricate facades and buildings that blended seamlessly with the surrounding sandstone cliffs. The city's water management system, including dams and cisterns, enabled the Nabataeans to thrive in this arid region.
