“The musical Sea Organ (morske orgulje) is located on the shores of Zadar, Croatia, and is the world’s first musical pipe organs that is played by the sea. Simple and elegant steps, carved in white stone, were built on the quayside. Underneath, there are 35 musically tuned tubes with whistle openings on the sidewalk. The movement of the sea pushes air through, and – depending on the size and velocity of the wave – musical chords are played…This masterpiece of acoustics and architecture was created by expert Dalmatian stone carvers and architect Nikola Basic …Many tourists come to listen to this unique aerophone, and enjoy unforgettable sunsets with a view of nearby islands. Famed director Alfred Hitchcock said that the most beautiful sunset in the world can be seen from precisely this spot on the Zadar quay”
