ペトラ遺跡はどうやって作られた？
Petra, located in Jordan, is called the "Rose City" and was built about 2,000 years ago by the Nabataeans. Amazingly, many of Petra's structures were carved directly into rock. They used tools like chisels and hammers to create beautiful temples and tombs. Recent studies show that they even designed an advanced water system to support the city.
