概要
Across the world, archaeologists have uncovered vast underground cities capable of sustaining thousands of people for long periods of time. These are not simple shelters or temporary hideouts, but complex systems with ventilation, water management, storage, and social infrastructure—built with long-term survival in mind.
In this episode, we explore why ancient societies invested so heavily in building beneath the surface, and why these structures are often treated as anomalies rather than part of a global pattern. Was the threat war, climate instability, repeated environmental crises—or something even more unpredictable?
We examine archaeology’s blind spots, the limits of siloed research, and why “refuge” is an incomplete explanation unless we ask what people were repeatedly seeking refuge from. From climate shocks to rare cosmic events, this episode reframes underground cities as a form of long-term risk management.
This is not an episode with easy answers—but with better questions about resilience, planning, and how civilizations survive uncertainty.
