In Croatia They call The sea-organ morske orgulje , Designed by Croatian architect Nikola Basic and opened to the public in 2005.

The sea organ was designed by Croatian architect Nikola Bašić as a way to make the shoreline in Zadar, formerly just a series of blocky concrete structures, a little more attractive.
The organ looks like a series of broad steps leading down into the water, but there’s actually very clever engineering hiding under the surface.
The lower steps allow water and air to flow in. That water and air is then funneled into resonant chambers under the steps, and pushed out through the channels on the upper stairs, seen here….
