The third- to fourth-century A.D. Roman fort at Umm el-Dabadib is likely built over an earlier pharaonic one. The oasis's Roman forts are found at the north, south, east, and west limits of the oasis, often near water supplies. Unlike others in the Roman world, they are made of mud brick, not stone. A walkway on top allowed soldiers to survey the surrounding area. The primary function of the forts was probably not defense as their walls are, for the most part, only one brick thick. However, especially from a distance, their massive appearance conjures up the might of the Roman Empire, so the facades must have deterred nomadic attackers while the forts performed their real function--administration of the empire's southern limits.

Deep in the Libyan Desert, 125 miles west of Luxor, lies Kharga, Egypt's largest oasis. The North Kharga Oasis Survey (NKOS), of which I am co-director, has established that this remote area--more than 100 miles long and from 12 to 60 miles wide--was continuously occupied throughout Egyptian history. We now know that it is home to an extraordinary variety of sites, including prehistoric rock art, Neolithic encampments, pharaonic monuments and burials, Roman settlements and water-supply systems, and the stars of the oasis--five unique Roman forts that guarded this part of the empire's southernmost frontier. Newly discovered ancient graffiti has even provided the name of a previously unknown ruler, King Aa, in power around 3000 B.C., who sent an expedition to this remote area. The NKOS's results are also changing our understanding of ancient Egypt's connections with its neighbors. We can now show that Kharga played an important role in trade between Egypt and other parts of Africa, from the Old Kingdom up through the modern period.
