The Temple to Poseidon in the Portus Magnus of Alexandria 🌊🏛️

Since 1992, Goddio and his team have been mapping the ancient port, uncovering monumental remains that match Strabo’s account of a grand temple to Poseidon:

  • 🏛️ Limestone ashlar masonry and pink granite columns scattered over 3,000 m²
  • 📐 3‑D stereophotogrammetry revealing the temple’s vast scale and precise layout
  • 👑 Insights into the Ptolemaic dynasty’s architectural ambition and religious life
