Zadar has a unique combination of architecture and music, the wordly known Sea Organ. It is located next to the installation Greeting to the Sun, and it represents an organ whose sound is produced under the influence of the energy of the sea, rather waves and tides.
The Sea Organ has been gently formed out of stone and returned to the sea. It stretches out on a surface of seventy meters of Zadar's coast, under which on the level of the lowest seated 35 pipes of different lengths, diameters and descent are installed. When the most beautiful sunset illuminates the waterfront, the play of light of the Greeting to the Sun accompanies the rhythm of waves and the sounds of the Sea Organ.
