Season 40

Vikings stood among the fiercest warriors in history. Yet only a select few bore the era's ultimate instrument of power: the feared Ulfberht sword. Forged through a process that would remain a mystery to their rivals for centuries, the Ulfberht fused revolutionary technique with artistry. Widely regarded as one of the finest swords ever crafted, it endures as a formidable weapon more than a thousand years after it last tasted battle. But how did Viking smiths design and forge the Ulfberht, and what role did it play in history? NOVA now applies cutting-edge science alongside old-fashioned investigative sleuthing to reconstruct the Ulfberht and finally reveal the Secrets of the Viking Sword.
