Ancient defensive wall found at Oued Beht site in Morocco
Archaeologists uncovered a large ancient wall at the Oued Beht site in northwestern Morocco during excavations in 2023.

New construction reveals past complexity
The structure dates between 4,000 and 3,500 years ago. It represents the earliest known large-scale defensive construction in North Africa outside the Nile Valley. This discovery indicates that local communities were actively shaping their environment during the second millennium BC.
Possible reasons for building walls
Researchers believe these structures relate to competition over land and resources rather than invasions. The findings suggest groups needed protection against increasing pressure within the landscape. Previous work at the site already identified an agricultural complex from around 5,400 to 4,900 years ago.
