In this episode of GL Deep Dives, we turn our focus to Greece — but not for myths or temples. Instead, we explore the Hellenikon Pyramid, a little-known structure that defies explanation. Older than the pyramids of Egypt? Possibly. A tomb, a fortress, or something far more mysterious? The truth is still buried in stone and speculation. Join us as we uncover the theories, controversies, and archaeological puzzles surrounding this overlooked ancient wonder — and ask what it means for our understanding of early European civilization.
