The sea on the edge of the ancient city of Zadar, the blue sea waves undulate. After walking through the beautiful seaside trail, you can see the famous wave organ and hear the intoxicating sound of the piano from the sea (the shape of the keys on the shore). Designed by designer Nikola Basic in 2005, the world's unique ladder wave organ was built by the sea. The organ is about 70 meters long and 35 tubes of varying calibres are implanted in the sea in parallel. Whenever the waves enter the pipe, different tones and notes will be played and music will be played throughout the year. The wave organ has won the European Urban Public Space Award. I really like this attraction.
