Season 2

2026 · 3 episodes · Last episode: 2 months ago

Cut off from the mainland, islands are worlds unto themselves — isolated, enigmatic and often hiding extraordinary secrets. “Mysterious Islands” returns for a new season, traveling to remote locations to uncover stories shaped by time and isolation. On Greece’s Keros, hundreds of deliberately shattered Bronze Age figurines are uncovered, hinting at lost rituals. On Ethiopia’s Daga Island, mummified medieval emperors reveal a hidden chapter of history. In Argentina, a perfectly circular floating island rotates within a circular lake, defying easy explanation. And in Hungary, skeletal remains beneath a monastery reignite a centuries-old mystery. Using CGI, archival material and expert analysis, “Mysterious Islands” investigates the truth behind these enduring enigmas.

    In Budapest, beneath the ruins of a medieval monastery on Margaret Island, archaeologists uncover the victim of a medieval killing — his identity lost, and his death shrouded in secrecy — but what led to this violent end? In Italy’s Venetian Lagoon, the shifting sandbar Bacan has suddenly stabilized, defying its natural cycle and raising new questions about the forces reshaping it. On Denmark’s Als, a buried boat surrounded by weapons hints at a forgotten conflict. Was it lost in battle or offered in ritual? And on Ethiopia’s Daga Island, mummified emperors lie hidden within a monastery, their presence tied to power, faith and enduring legend.
