• Hear how a Roman gold hoard worth a fortune lay hidden under a parking garage for eighteen centuries — until an excavator split it open

• Trace the story of Trier's devastating witch trials, where a chief judge was destroyed by the very system he once enforced

• Follow Karl Marx's roots from a rabbi's family in the Jewish quarter to the modest house where history's most famous critic of power was born

• Learn why Trier's greatest monuments survived not by design but by accident — a monk's strange devotion, a dead man's wager, and a lie that turned out to be true
