The Mermaid of Zennor
Under the sea, between the Lizard and the Isles of Scilly is the lost land of Lyonesse, drowned by a great storm long ago. There were woods, fields and 140 parish churches. It stretched far to the west with a watchtower at the farthest point.
Old folks say that when such a storm is about to happen again, you can hear the bell of the drowned village of Chy an Mor ringing out a warning and no good will come of it.
