35-Metre Circular Temple Linked to the Nile Transforms What We Know About Pelusium

A 35-metre circular structure, supplied by Nile waters and concealed beneath the desert for roughly 2,200 years, is reshaping what was known about Pelusium. Unearthed in northern Sinai, this unusual temple includes channels, reservoirs and a monumental basin that may have hosted religious ceremonies devoted to the river’s water and fertile silt.

Circular temple astonished archaeologists

The sanctuary was discovered at Tell el-Farama, the site occupied by the ancient port city of Pelusium at the eastern edge of the Nile Delta. Egypt’s Ministry of Tourism and Antiquities says excavations began in 2019, although the building’s true purpose only became clear once it had been fully uncovered.

At first, the red-brick structure was thought to have possibly been the seat of the municipal senate. Hesham Hussein, head of the Central Administration of Lower Egypt and Sinai Antiquities, said this interpretation became less convincing after channels, water stores and religious features were found around the circular building.

How did the Nile-connected structure operate?

The complex was arranged around a circular basin measuring about 35 metres across. At its centre stood a square pedestal, which most likely supported a colossal statue of Pelusium, a local deity linked to the mud, silt and waters that ensured the fertility of land near the river.

The team found channels and reservoirs linked to an ancient branch of the Nile. River water and sediment were also discovered inside the basin. For the researchers, these traces reinforce the theory that water was introduced into the space in a controlled way and that it was used for symbolic activities or sacred ceremonies.

Water held a central place in Egyptian rituals

Research into Egyptian religion indicates that water was associated with purification, renewal and the origin of life. Egyptologist Joachim Friedrich Quack, in his examination of concepts of purity in ancient Egypt, noted that ritual preparation involved a range of cleansing actions before contact with divine images and spaces.

• Purification of priests before ceremonies;
• Cleansing of objects, altars and religious offerings;
• Representation of the primordial waters of creation;
• Symbolic renewal of life and fertility.

The Egypt Exploration Society likewise notes that many temples had sacred lakes where priests performed purification baths. At Pelusium, however, the combination of a large circular basin, reservoirs and a direct connection to the Nile forms an uncommon complex that could broaden understanding of regional cults.

Pelusium linked peoples and traditions

Its strategic position near the Nile’s mouth made Pelusium a fortress, trading port and customs post during different periods. Egyptian, Greek and Roman influences reached the city, and this is reflected in the temple’s architecture, which combines local traditions with approaches used across the Mediterranean world.

Hisham El-Leithy, an official of Egypt’s Supreme Council of Antiquities, described the discovery as highly significant. Archaeological layers show that the temple was built in the second century BC and remained in use until the sixth century AD, spanning approximately eight centuries of political and religious change.

The discovery may still reveal further secrets

Beyond its rare architectural form, the temple demonstrates that religion, hydraulic engineering and urban life were closely intertwined. The structure also underlines Pelusium’s importance as a cosmopolitan centre, where the Nile supported the economy and helped shape shared beliefs.

Now, every channel, fragment and layer of silt must be preserved and studied before irreplaceable information is lost. The discovery offers a powerful warning: protecting archaeological sites today means ensuring that future generations can still understand how ancient societies turned nature into memory, faith and identity.
