These include the remains of a Neolithic farm settlement and many papyri written both in ancient Egyptian and in Arabic. The city of El Faiyum (1986 pop. 213,070), located in the southeastern part of the governorate and its capital, is the region's trade, distribution, manufacturing, and transport center. Industries include cotton ginning, wool and cotton spinning and weaving, dyeing, tanning, and cigarette manufacturing.
