```Petra's Al-Khazneh ("The Treasury") is one of the most famous examples of rock-cut architecture. This gorgeous archaeological site is Jordan's most popular tourist attraction, and one that has made cameos in a variety of popular media, most notably in the 1989 film, "Indiana Jones and the Last Crusade." The building of Petra's iconic structures began as early as 213 B.C. by a society of nomadic, pre-Islamic Arabs known as the Nabateans. Situated along several major trade routes, the city served as a pivotal trading hub in the region.```
