El-Kharga:

Research has found that the Oasis has been inhabited since prehistoric times, and that there was once a huge lake here, on which man and animals used to live around it, when it was dried they moved to the Nile valley. Evidences show that Dakhla there were remains dating to the Old Kingdom have been found. The archaeological remains unearthed at 'Ayn Asil in the last twenty years suggest that this oasis must have played an important role under the sixth Dynasty of the Egyptian kings. Placed at the junction between the track called Darb el-Tawil, leading directly to Middle Egypt, and the two caravan routes which via Kharga gave access to a number of tracks to Upper Egypt, 'Ayn Asil was originally a small square fortified enclosure. During the reign of Pepi II, the Governors of the oasis built a large palace and obtained the permission to erect small sanctuaries for themselves.

However, the palace was eventually destroyed by the fire, then it became abandoned, but then was reconstructed & restored again during the beginning of the Intermediate period in some places of the building. It retained some wooden elements like doors or columns, that collapsed and burned on the spot.

It is worth visiting that area as the exposed area of the palace is quite striking. Even though over 4,000 years have passed since it was last built, but the thick mud-brick walls, clay floors and limestone column bases still give a very good impression of what the building must have looked like. There was also found a large necropolis, called Qila el-Dabba, clearly distinguished by the presence of seven large mastabas, massive rectangular mud-brick superstructures that covered the tombs of the local Governors.
Several ancient cemeteries have been found in Dakhla, and it is evident that the area was occupied continuously up to the Roman period, when the Oasis seems to have been heavily populated and intensely cultivated. Hundreds of Roman wells still survive. The most impressive remains of this period are to be found at Amheida, a large settlement half-covered by sand surrounded by an extensive necropolis.
The capital, Mut, named after the ancient goddess Mut, goddess of fertility and prosperous.
