carved out of the desert 2,000 years ago, it was built by a local tribe called the nabataeans. well, in 2016, i went to see efforts to protect this ancient site from the elements, and from tourists like me. this split in the rocks is called the siq, and it was the only entrance, or way in and out of the city. and it would've been heavily guarded to stop anyone from sneaking in and trying to take over. it's just breathtaking. at the end of the siq is the most famous part of petra, the treasury. an elaborate temple carved from the sandstone. just take a look around, you can see how popular this place is. it's the most visited
