Using non-invasive geophysical methods such as magnetometry and electrical resistivity tomography techniques, archaeologists have discovered a massive, 2,500-year-old mudbrick building that had been buried beneath alluvial deposits and submerged sediments in Egypt’s Nile Delta for thousands of years.
The structure was located as part of a recent archaeological project within the Palamon Hill carried out by researchers from the Polish Center for Mediterranean Archaeology and cooperating local authorities. The building dates back to the late era of ancient Egyptian history, specifically the Twenty-Sixth Dynasty.The discovery of this large ancient building is of great archaeological interest, since most ancient structures are not well preserved in the delta region due to exceptionally high groundwater levels, which caused the destruction of almost all archaeological materials.
Therefore, this very large hidden monumental building provides an unprecedented in situ record of the nature of urban planning and administrative arrangement in the ancient Egyptian delta at a crucial time in Mediterranean and Egyptian history.
Discovery of the Nile Delta: a massive 2,500-year-old structure
Non-destructive geophysical survey techniques (magnetometry and electrical resistivity tomography) were used to identify a large-scale ancient site (Palamun Hill) with remains of archaeological interest under several meters of Nile River silt, without intrusive excavations.
The archaeological survey team created a high-resolution geophysical map of the footprint of the site’s mudbrick walls (built in the 26th Dynasty) by identifying magnetic anomalies and measuring electrical resistivity in the silt-laden soil across the entire site.
Maintaining groundwater levels
According to research published by the British Museum, excellent examples of well-preserved mud bricks are likely not to be found in the Nile Delta due to the natural high water table and wet, silt-filled environment.
Most of the ancient material from this area has likely been degraded or compressed by tphononic processes that have accumulated in that area for thousands of years. This discovery is remarkably important from a scientific perspective because the remains of the foundation of these structures provide an exceptional opportunity (eg:
a time capsule) to understand the architectural techniques used in the late era of Egyptian civilization.
Center of administrative authority
Balamun Hill was built about 2,500 years ago during the Sawi Period (26th Dynasty) when Egypt experienced a cultural and political renewal. Balamun Hill served as a strategic location on the northern border. It was a major administrative and religious center. The large size of this complex shows that it may have served as a residence for the elite or the seat of Egyptian government and reflects the organization and centralization of the population of the Delta region during that period.
Surviving the annual Nile flood waters
According to the UNESCO World Heritage Center, the construction of this large structure serves as a model for how the ancient Egyptians built their cities on swampy terrain. The thickness of the mud-brick walls also indicates that the engineers who designed this structure had great knowledge about building structures that could survive the floodwaters of the Nile River every year. Analysis of the general plan will also enable historians to understand the transfer of power and the importance of the delta region as a strategic location for trade in the Mediterranean and as a place of defense against military attacks.
