Folk tales of islands and submerged lands - stories of countries both isolated and connected by water.

Folk tales flow around the world like rivers, spilling over into imprints where history has left its mark; where cultures have been uprooted, seabeds scoured and villages drowned (but never forgotten).

Follow the current out from Welsh waters, where all these stories begin, into the vast ocean. Here be sea monsters and swan girls, displaced people and rain-makers, toilet demons and talking catfish – so come on in, the water's fine.
