Diy-Gid-Biy, Archaeological monument in Mandara Mountains, Far North Cameroon.

Diy-Gid-Biy is a cluster of sixteen archaeological sites in the Mandara Mountains with dry stone structures rising above the Shikewe watershed, featuring terraces and platforms built from naturally fitted granite stones. Excavations have uncovered ancient ceramics, iron objects, grinding tools, and mortars that reveal how people lived and worked at these ancient settlements.

These sites were occupied across several centuries, with some structures dating to the 15th century while earlier settlements reached back to the 13th century. The long span of habitation shows that this mountainous location has been an important center for local communities for many generations.

The name Diy-Gid-Biy comes from the Mafa language meaning 'place of chiefly residence', showing how deeply this site connects to local tribal identity. Today, people from the area still recognize these ruins as an important part of their ancestral heritage and community history.

The site sits in mountainous terrain where paths can be uneven and steep, so wear sturdy shoes and bring water. Local guides are essential for exploring the separate archaeological zones and getting the most from your visit.

At DGB-1, archaeologists found copper and glass objects that did not come from the Mandara region, the only site in the area showing contact with distant peoples. Iron spear tips and arrowheads lay beneath the floor, and a ground greenstone axe and quartz hammerstones were also recovered.
