A short account of Shivta, given by your Israel & Jerusalem private tour guide
"While there are many Arabian tribes who use the desert as pasture, the Nabataeans far surpass the others in wealth although they are not much more than ten thousand in number; for not a few of them are accustomed to bring down to the sea frankincense and myrrh and the most valuable kinds of spices, which they procure from those who convey them from what is called Arabia Eudaemon" (Diodorus of Sicily, 1st century BCE).
Located in the westrn-central Negev desert, is the ancient city of Shivta. To be more exact – these are the impressive ruins of this city. One should visit the city because of what it can show, but the real story is that of the above mentioned Nabateans, the people who, in this country, lived in Shivta, Avdat and in four other cities in the Negev, as well.
