This week, the series journeys into these subterranean realms to question what truly lies below the surface. From structures carved by early man to caverns shaped by nature over millennia, each discovery presents a new puzzle.
Are these underground networks merely remnants of a forgotten past, or do they hold secrets that defy modern explanation? The episode examines the evidence left behind in these dark places, seeking answers about the civilizations that built them and the powerful myths they inspired.
