Órgano del mar-sea organ

Built in to the middle of the Croatian Adriatic coast, the Sea Organ (Croatian ‘Morske orgulje‘) was designed by architect Nikola Bašić and built by Dalmatian stone carvers. After the devastation of World War II, chaotic reconstruction transformed the sea front in to a giant, unbroken concrete wall. It remained that way until 2005, when an urban renewal project transformed the coast again. At the end of the vast promenade, Bašić designed a 70 metre long stair case that descends in to the Adriatic sea. Underneath the steps are 35 organ pipes built in to subterranean tunnels. A column of air, pushed in turn by the waves, blows each organ pipe. The sound emerges above ground through labiums (whistles), which play 7 chords of 5 tones each.
