8 Marvels of the World
Petra is an ancient Nabataean city located in Jordan, whose name means "rock" in ancient Greek.
As early as the 6th century B.C., the Nabataeans made it a prosperous stage along the route of caravans carrying pearls and turquoise, ivory and silk, incense and spices. Petra was a real crossroads between Arabia and the Mediterranean, and between Egypt and Syria.
Having fallen into oblivion in the modern world, it was rediscovered by the Swiss explorer Jean-Louis Burckhardt in 1812.
The emblematic building in Petra is the Khazneh, with its monumental facade carved into the rock face.
