Sahara's 55-Meter 'Antenna' Tomb Finally Dated to 2467–2150 BC 2026

The 55-meter 'antenna' tomb in the Sahara has finally been dated to between 2467 and 2150 BC, solving an eight-year mystery since its excavation. Located in a gravel plain of northern Western Sahara, this oval stone mound with two rows of slabs extending eastward like antennas has intrigued archaeologists since it was first opened in 2018.

Now, a team from the University of Girona and the Sahrawi Ministry of Culture has used advanced dating techniques to pinpoint its age, offering a rare glimpse into the funerary practices of ancient nomadic peoples in one of the world's most inhospitable regions.

What Is the 'Antenna' Tomb and Where Was It Found?

The monument sits near Wadi Lawash el Telli, at the eastern edge of Sluguilla Lawash, an area renowned for its prehistoric rock art with 1,143 engraved rocks. From above, the structure resembles a mound with antennas, hence its nickname. The site is so dry and remote that shepherds only visit when heavy rains occur.

Excavated in April 2018, only half of the tomb was deliberately opened, revealing a single individual. The burial was simple: the body lay supine on the natural ground, head pointing south, legs flexed westward, without a pit. A modest adornment of four ostrich eggshell beads accompanied the deceased.

How Did Archaeologists Finally Date the Tomb?

Initial dating attempts using collagen analysis failed, likely due to poor preservation in the harsh desert environment. In 2025, the team turned to a different technique—likely radiocarbon dating of the ostrich eggshell beads or other organic material—to successfully establish the timeline. This methodological shift proved crucial.

The resulting date range of 2467–2150 BC places the tomb in the late third millennium BC, a period when nomadic pastoralists roamed the Sahara. The findings were reported by Archaeology Magazine, highlighting the collaboration between Spanish and Sahrawi institutions.

Why Does This Discovery Matter?

This dating provides a concrete chronological anchor for a type of monument that has been poorly understood. The 'antenna' tomb is part of a broader tradition of funerary structures in the Sahara, but precise dates are rare. Knowing that this individual was buried around 4,500 years ago helps researchers trace the spread of cultural practices across North Africa.

Moreover, the burial's simplicity—no elaborate grave goods, just a few beads—suggests a society that valued modesty in death or had limited resources. It also underscores the adaptability of ancient peoples to extreme environments.

• The tomb dates to 2467–2150 BC, bridging a gap in Saharan prehistory.
• Only half the structure was excavated, preserving it for future study.
• The burial contained one adult aged 25–35, with ostrich eggshell beads.
• Collagen dating failed; a newer method succeeded in 2025.
• The site is near significant rock art, indicating a rich cultural landscape.

What Does the Burial Reveal About Ancient Saharans?

The body's position—head south, legs west—may hold symbolic meaning, though interpretations vary. The ostrich eggshell beads are among the earliest known personal ornaments in the region, suggesting trade or craftsmanship. Such beads were often used in life and death, possibly indicating status or identity.

The lack of a formal pit and the placement on natural ground hint at a rapid burial or specific ritual practices. Compared to other Saharan tombs, this one is relatively modest, which might reflect the individual's social standing or the community's customs.

What to Watch Next in Saharan Archaeology

Future excavations at Sluguilla Lawash could uncover more tombs and artifacts, helping to build a regional chronology. The team's success with alternative dating methods may encourage similar approaches at other sites where collagen is poorly preserved.

Additionally, the rock art at the site—1,143 engraved rocks—remains a treasure trove for understanding symbolic expression.
