The people living in these areas were death-worshippers. Their commemorative funerary terra cotta is evidence of this, whether they be this phallic urn, large pots to put the deceased into, heads, or vases.
What constitutes Bura work is from one of three types of sites. It is not always easy to distinguish them, but the UNESCO website informs us more precisely:
- sites with burial mounds characterized by a particular kind of large pot as a coffin, or anthropomorphic funeral urns made up of surmounted heads of statuettes, made to be placed on the ground and, in the case of the Asinda-Sikka, containing human skeletons. These sites come from two distinct archaeological groups:
- sites for religious altars and ritual ceremonies characterized by accumulations of large blocks of stone forming a flattened mound or flat area for the Asinda-Sikka, Karey-Tondi, Jajé-Tondi and Mebera-Tondi. There, one finds fragments of the feet of tripod vases and fragments of pottery in the form of small painted cylinders.
- sites of dwellings difficult to identify. But the discovery of fragments of tripod vases and sometimes of small accumulations and alignments of large blocks of stone testifies to a human presence. Chips of quarzites or flint can also be found on the site along with arrows and thin ceramics from the Kosendo-Gorizo located to the west of the burial mound, behind a hill.
The general layout of the Bura system seems to focus on two poles, the religious burial mound and the religious altar. The burial mound is almost always located in a protected place. On this surface, only 150 m² was dug, up to the level of the skeletons at 3 meters depth.
