Valley of Al-Haiz is located near the western edge of Bahariya depression beside the black desert in Bahariya Oasis.
During the time of the Romans this valley was much greener and arable so it was one of the most important places in Egypt for producing wine.

The Remains of a winemaking factory were discovered in Al-Haiz Valley in 1988 and in 1940 foundations of a palace and other large and splendid mansions were discovered by Ahmad Fakhry.
