Central Africa

In the northwestern region of the Central African Republic, there are megaliths that were created for various purposes (e.g., burial, ritual performances). Between late 3rd millennium BCE and mid-2nd millennium CE, megaliths (e.g., monuments, cairn burials) were constructed in the regions (e.g., Eastern Adamawa, Oubanguian Ridge, Chad/Congo watershed) in Central African Republic and Cameroon, throughout various periods (e.g., Balimbé: 2000 BCE – 1000 BCE; Early Gbabiri: 950 BCE – 200 BCE; Late Gbabiri: 200 BCE – 500 CE; Bouboun: 500 CE – 1600 CE), for various purposes (e.g., ritual practices, territorial marking).
