Egyptian archaeologists have announced the discovery of a rare religious structure at Tell el-Farma (the archaeological site of ancient Pelusium, a strategically vital border city on the northeastern edge of the Nile Delta in North Sinai) after six years of excavations. The temple, dedicated to the local deity Pelusios — whose name likely derives from the Greek word for mud or silt — centres on a massive 35-metre circular basin once fed by a branch of the Nile, symbolically linking the god to the river's fertile floodwaters. The find rewrites understanding of Pelusium's role in the ancient world: its architecture blends Pharaonic, Hellenistic, and Roman styles, and evidence shows the site was in continuous sacred use from the second century BC to the sixth century AD, confirming the city as a major crossroads of religious and cultural exchange between Egypt and the broader Mediterranean world.
