In the Mafa language, Diy-Gid-Biy means “ruin of the chief’s residence”.
It comprises 16 archaeological sites featuring dry-stone architecture (terraces, platforms, walls, and stairs) spread across seven villages in the Mandara Mountains.
These structures date from the 12th to the 17th centuries and were built by an unknown civilization.
The Mafa people settled there starting in the 15th century and now use the sites primarily as religious and spiritual places.
In addition to the ruins, the landscape includes agricultural terraces, dwellings, tombs, sacrificial sites, and artisanal activities on the mountain slopes.
It bears unique witness to a vanished civilization and a rare form of dry-stone architecture in Sub-Saharan Africa (criterion iii).
The area covers approximately 2,500 hectares and is located near the border with Nigeria (near the Sukur landscape).
It forms a living example of the harmony between man, culture, and mountainous landscape.
