Beyond the cliffs of Cornwall, past the last fishing boats and into the restless Atlantic, legend speaks of a kingdom lost to the sea. Fields, forests and towers lie drowned, yet some say their bells still toll beneath the waves. This is Lyonesse… Britain’s Atlantis.

In this episode of Dark Cornwall, we follow the currents of myth and memory — from Tennyson’s haunting vision of Arthur’s final journey to the traces of ancient forests, stone walls and reefs that hint at a world reclaimed by the ocean. We sail over the perilous Seven Stones, stand on the shingle bar of Loe Pool, and listen for the echoes of a land that may never truly have vanished.

Step into the fog, hear the bells, and decide for yourself what lies beneath the tide.
