The white horses in the sea and the sea organ at Zadar, Croatia thrill tourists from around the world. A man made experiment in harnessing the power of the ocean waves to create musical sounds. There are seven steps to the sea. The stairs extend for about 70 meters along the coast, under them, at the lowest sea-tide level, 35 pipes of different lengths, diameters and tilts were built in vertically to the coast and they raise aslant until the paved part of the shore and end in a canal (a service corridor). On the pipes there are LABIUMS (whistles), which play 7 chords of 5 tones. Above the canal there are perforated stone stairs through which the sound comes out, the air pushed by the sea.
A collaboration of man and nature. Enjoy the video and check out Zadar's website at http://www.zadar.travel/en/about-zadar
P.S. The image above is not from Zadar but is in fact the Santa Monica Pier in Santa Monica, Los Angeles, California. It's available in the Art of the Oceans gallery. Hopefully, one day I might get to Zadar.
