Sea Organ is situated on the western end of Zadar´s Riva, extending for about 70 meters along the coast and can be observed as a differently shaped part of the coast which consists of several stairs that descend into the sea. Under the stairs, at the lowest sea-tide level,  there are 35 pipes of different lenght connected by seven central pipes. 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. As moving water moves through a submerged plastic pipe in the sea, it moves air through these tuned pipes, generating incredible sounds through the openings seen here on the stairs and on top of the walkway.

This masterpiece of acoustics and architecture was created by expert Dalmatian stone carvers and is constructed according to the project made by Croatian architect Nikola Bašić with the help of several experts. In 2006 Nikola Bašić received the European Prize for Urban Public Space in Barcelona for his Zadar Sea Organ project, as the best among 207 candidate projects from across Europe.

This site is a blend of human ideas and skills and the energy of the sea, waves, tide and flood, a place for relaxation, contemplation and conversation. It’s a powerful concept that brings people to the shore, and gets them to slow down and pay attention to nature. Thanks to the Sea Organ music project, the inhabitants of Zadar have been restored once more to their relation with the sea.
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. That was how he described it after his visit to Zadar, a visit he remembered throughout his life by the meeting of the sinking sun and the sea.
