Set in a depression covering over 2000 sq. km., Bahariya Oasis is surrounded by black hills made up of ferruginous quartzite and dolorite. Most of the villages and cultivated land can be viewed from the top of the 50-meter-high Jebel al-Mi'ysrah, together with the massive dunes which threaten to engulf some of the older settlements. The Oasis was a major agricultural center during the Pharaonic era, and has been famous for its wine as far back as the Middle Kingdom. During the fourth century, the absence of Roman rule and violent tribes in the area caused a decline as some of the oasis was reclaimed by the sand. Wildlife is plentiful, especially birds such as wheatears; crops (which only cover a small percentage of the total area) include dates, olives, apricots, rice and corn.

Over time, the Bahariya Oasis has had a number of different names. It has been called the Northern Oasis, the Little Oasis, Zeszes, Oassis Parva and the especially during the Christian era, the Oasis of al-Bahnasa, along with various other names. At one time, the Bahariya Oasis, as well as most of the rest of what is today referred to as the Western (or Libyan) Desert, was the floor of an immense ocean. Yet from about 3000 BC until the present, almost no rainfall graces this part of the world, so groundwater is its life blood.
