El Sarag, located near the ancient site of Contra Apollonos (modern El-Ridisiyah), is one of Upper Egypt’s most fascinating yet lesser-known archaeological sites. Situated approximately 20 km south of Edfu on the east bank of the Nile, the fort occupied a strategic position protecting routes that crossed the Eastern Desert toward the Red Sea.

The fort was established during the Roman period and remained in use throughout the Byzantine era, between the 4th and 8th centuries AD. Soldiers stationed here monitored trade routes, secured travelers, and protected valuable goods moving between the Nile Valley and ports along the Red Sea coast.

Archaeological excavations conducted between 1997 and 2005 revealed much more than a military installation. Researchers uncovered the remains of homes, Coptic churches, monasteries, workshops, storage facilities, and even Islamic coins, illustrating centuries of continuous occupation and cultural exchange.

The settlement served as an important stop along desert routes connecting Edfu to Marsa Alam and El Sarag to the ancient Red Sea port of Berenice. During the Byzantine period these roads became popular pilgrimage routes for Christians traveling through Egypt. Later, they were used by Muslim pilgrims journeying north from Sudan and southern Egypt.

Today, the ruins offer a rare glimpse into everyday life on Egypt’s frontier, where soldiers, merchants, monks, and travelers interacted for centuries. The site can often be viewed directly from a Dahabiya sailing along this section of the Nile, and visits may be possible depending on archaeological activities.
