Zerzura
Zerzura (Arabic:زرزورة) was a mythical city or oasis.
Zerzura was long rumored to have existed deep in the desert west of the Nile River in Egypt or Libya. In writings dating back to the 13th century, the authors spoke of a city which was "white as a dove" and called it "The Oasis of Little Birds". In the Kitab al Kanuz, Zerzura is said to be a city in the Sahara full of treasure with a sleeping king and queen. The city is guarded by black giants who keep anyone from going in and coming out. However, this may be a reference to the black Tebu people, nomads in Chad and Libya whose ancestors used to raid oases out in the Sahara.
