NEW TPO 3 What does the speaker point out about the city's water system?

[00:00.00](N) Listen to a talk in a history class.
[00:01.00](M-Am) Petra is an ancient city located in present-day Jordan. It was established as early as 312 B.C. as the capital city of the Nabataean kingdom. The Nabataeans were skilled traders, and Petra became a major trading hub because of its strategic location along caravan routes that linked the East and West.
[00:02.00]Petras architecture is unique because much of it was carved directly into the rose-red cliffs of the region. The most famous structure in the city is known as the Treasury, but it is actually a tomb. The city also featured a complex system to manage water, including dams, cisterns, and water channels, that allowed it to thrive in the arid region. These advanced water-engineering structures were crucial for the survival of its inhabitants given the low amount of moisture that was available naturally.
[00:03.00]In addition to its architectural and engineering feats, Petra is significant for its cultural exchanges. As a trading center, it facilitated the exchange of goods, ideas, and customs between diverse peoples. This blend of cultures is evident in the various architectural styles seen in the city, which include influences from Greek, Roman, and indigenous Nabataean designs. Next, we will explore how archaeologists rediscovered Petra in the nineteenth century.
