The 230-foot-long Zadar Sea Organ (or Morske orgulje) in the Croatian town of Zadar, is a series of marble steps that produces music powered by the waves of the Adriatic Sea. Below lies a series of narrow channels that connect to 35 organ pipes. Each set of steps holds five organ pipes each and is tuned to a different musical chord. As the waves lap against the steps, they push air through the pipes and out whistle-holes in the surface above, making a harmonious and completely random musical arrangement.
Chaotic reconstruction work was undertaken in an attempt to repair the devastation Zadar suffered in the Second World War. The frantic reconstruction turned much of the sea front into an unbroken, monotonous concrete wall.
The device was made by the architect Nikola Baši? as part of the project to redesign the new city coast (Nova riva), and the site was opened to the public on 15 April 2005. The waves interact with the organ in order to create somewhat random but harmonic sounds.
The Sea Organ has drawn tourists and locals alike. In addition, white marble steps leading down to the water were built later. Concealed under these steps, which both protect and invite, is a system of polyethylene tubes and a resonating cavity that turns the site into a large musical instrument, played by the chance-based results of the wind and the sea waves.
