A large structure more than 2,500 years old has been detected beneath Egypt’s Nile Delta. Discovered at the site of Buto, it could be a secondary temple or a tomb, revealed through a mix of satellite data and underground scanning. The finding highlights how newer technologies are helping archaeologists explore places that were once too complex or waterlogged to study properly.
The site of Tell el-Fara’in, identified as ancient Buto, is known for its complicated history. It was occupied for thousands of years, from the Predynastic period to the Early Islamic era, leaving behind layers that are difficult to separate. On top of that, regular flooding in the delta has made excavation even harder.
To deal with this, a team from Kiel University and Egypt’s National Research Institute of Astronomy and Geophysics used a combined approach. Instead of digging blindly, they relied on multiple technologies to locate what was buried before starting targeted drilling.
A “Scan” Of The Ground Reveals Hidden Remains
The researchers first turned to satellite imagery to spot unusual patterns in the soil. According to the study published in __Acta Geophysica__, these patterns suggested the presence of buried structures.
They then used electrical resistivity tomography, a method that sends electrical currents into the ground to measure how the soil responds. This produces a 3D model of what lies below the surface; essentially a kind of underground scan. The research team stated that:
“The results of this study demonstrate the effectiveness of combining geophysical measurements and remote sensing data, which gave a very accurate vision in detecting buried settlements in a complex region.” they added in the paper, “3D inversion algorithms were particularly effective in delineating buried mudbrick walls and architectural structures, significantly enhancing our understanding of site formation processes.”
Objects Discovered May Have Served a Spiritual Role
The structure measures about 65 by 80 feet and lies between 10 and 20 feet underground. It dates back to Egypt’s 26th Dynasty, also known as the Saite period. A period marked by a return to stability after a time of unrest. Power was reestablished, and older traditions were brought back into focus. It ended with the Persian conquest of Egypt.
Inside the discovery, researchers found a range of religious artifacts. According to the study, several amulets depict deities such as Isis, Horus, Bes, and Wadjet, a goddess closely linked to Buto. One particularly unusual amulet shows a hybrid figure combining a baboon, a falcon, and the dwarf god Pataikos. The team also uncovered a steatite scarab bearing the name of Thutmose III, likely used as a seal and considered one of the most important finds.
Other objects include a small offering basin, a relief of Hathor, and figurines, pointing toward a religious or symbolic function for the structure, even if its exact role is still unclear.
A Landscape Sculpted by Engineering and Moving Waters
The foundation of the building reveals how ancient builders adapted to the delta’s unstable conditions. The authors said that the ground was deliberately leveled using a uniform sand layer before construction began. This suggests organized planning and significant preparation, likely necessary in a region prone to flooding.
The study also pointed to a roughly 1,500-year gap in occupation at Buto. As explained by the authors, this break was probably caused by changes in waterways that made the area less suitable for settlement.
When people returned, they settled further east, in areas that had not been used before. There, archaeologists identified smaller structures and ovens. In the upper layers, they also found remains from the Ptolemaic and Roman periods, including pottery fragments, mud bricks, and limestone debris.
