Carved into the steps are narrow channels that connect to 35 organ pipes, each tuned to different meticulously arranged musical chords.
As the waves lap against the steps, they push air through the pipes and out whistle-holes in the surface above, making a harmonious and completely random musical arrangement.
But you don't see what's happening below the surface. You close your eyes and all you hear is a song like you've never heard before, one completely unique to the movement of the sea at that exact moment.
Take a listen: Here's what it sounded like at one particular moment, on one particular day. On any other day, it might sound completely different.
And this is the place where you can experience it yourself.
