omething strange is happening beneath the Earth... and the deeper you look, the more impossible it becomes to explain. From sealed passageways under ancient cities to vast tunnel systems that appear connected across continents, new evidence suggests something far older may be buried below us. In this investigation, we explore the secret tunnels beneath the Earth — mysterious networks carved through solid rock long before recorded history. Who built them, how far do they go, and why were they hidden?
