Appledore’s main estuary has some of the highest tides in Europe. There they build ships, fish, trade to the Americas and to Russia. It is an important and historic port. The rise of the water at high tide moves the clapper to strike the bell. Played by the movement of the waves, the bell creates a varying, gentle, musical pattern. As the effect of global warming increases, the periods of bell strikes will become more and more frequent, and as the bell becomes submerged in the rising water the pitch will vary.
