Seven Wonders Part 2: Petra - Jordan

At about 200 km south of Amman, the capital of Jordan, stands the "pink city" of Petra, Unesco World Heritage. The many temples, monasteries, baths and tombs that make up the site are directly cut into the rock.

It's just beautiful! Petra was the principal city of Nebateus at the end of the first century before Christ. It's amazing how Nebateus succeeded in developing efficient hydraulic systems to conserve water and building dams to divert the waters of the winter that once caused flooding in the city.
