An ancient military garrison discovered in the Sinai desert may hold clues to how the Egyptians defended the northeast gateway to their kingdom.
“This city was used to protect Egypt and as a gate to the Delta. It was a post of control. If you wanted to cross the Nile, you asked for permission before you crossed the bridge,” Abdul Maqsoud said.
Most Egyptian fortifications at the time were made of stone, not easily available in the Sinai. So Egyptians used seashells to strengthen the mud brick used to build the garrison, with a 15 meter thick and 12 meter high wall to discourage attack.
