A new archaeological study has identified 260 previously unknown monumental tombs in the Atbai Desert, a vast and still poorly explored region stretching across eastern Sudan between the Nubian Nile and the Red Sea Hills. The structures, known as Atbai Enclosure Burials, appear to belong to a mobile pastoralist culture that flourished during the fourth and third millennia BC, with some related examples reaching back even earlier.
That makes the earliest phases of this funerary tradition older than Egypt's pyramids, built centuries later on the Nile Valley's western edge. But these were not royal tombs of stone-cut corridors and written names. They were circular monuments in the desert, built by herding communities whose wealth moved on four legs.

The discovery was made through systematic remote-sensing work by the Atbai Survey Project. Using satellite imagery, researchers mapped circular and oval stone monuments across an enormous desert zone from Upper Egypt toward the Eritrean borderlands.
The study recorded 280 monumental structures in total, including 20 already known from earlier surveys. The remaining 260 were newly identified through satellite analysis.
Most are large circular stone enclosures containing internal burials. Some measure only a few meters across, while the largest reach more than 80 meters in diameter. Their scale suggests that these were not ordinary graves, but central places in the social and ritual landscape of prehistoric herders.
