Zadar Croatia's Sea Organ - Where waves make music


Zadar skyline

The medieval town of Zadar Croatia is a historic city on the Adriatic coast. While it has many wonderful sites such as the church of St. Dominus and the ruins of a Roman forum, it is also home to a truly unique architectural wonder that has captivated visitors from around the world, the Zadar Sea organ. Sitting on the stone steps and listening to the power of nature create one of a kind music is an experience you will definitely want to enjoy while visiting Croatia.


About an hour and a half north of Split and an hour north of Sibinik, old town Zadar is located on a small peninsula. You can find the wave organ at the water's edge, just outside old town. You will often see large cruise ships docked nearby. Also close by is the Monument to the Sun or Greeting to the Sun monument. This is a monument that features 300 solar panels in the shape of a circle. The glass panels absorb sunlight during the day. At night they power a light show representing the solar system and the orbits of the planets.


Beside the Monument to the Sun is the magnificent Sea Organ, or "Morske Orgulje" in Croatian. This is a unique audio-visual art installation that harnesses the power of the sea to create hauntingly beautiful melodies. These two innovative projects, have transformed a once-neglected stretch of concrete into a popular gathering spot making it the perfect place to sit down, relax and enjoy the beautiful sounds created by nature.

Concept and Design


The Sea Organ is the brainchild of Croatian architect Nikola Basic, who envisioned a way to breathe new life into the city waterfront. Zadar, with its interesting history dating back to Roman times, had suffered extensive damage during World War II. The postwar reconstruction left the shoreline with an uninspiring concrete wall. Bašić wanted to rejuvenate this area. His design aimed to reconnect the city with its maritime heritage while creating a new public space for people to enjoy.


This experimental musical instrument was only part of a project taken on by the city of Zadar to revitalize Zadar's Riva, the waterfront promenade. Built in 2005, Bašić's design blends with the existing landscape. Above the organ is a set of steps made of marble that descend into the Adriatic Sea. The steps of the sea organ are a gathering place for the citizens of Zadar and visitors alike with beautiful views of the Dalmatian coast. Beneath these steps though lies the true genius of the Sea Organ.

How the Sea Organ Works


The first natural musical organ, the Zadar sea organ functions as a giant, natural musical instrument powered by the rhythms of the sea. Beneath the marble steps are a series of thirty-five organ pipes that are essentially a series of polyethylene tubes of different diameters and lengths. These tubes are connected to resonating chambers, or air holes, built into the concrete layer below the stone stairs. 


The sea forces water and air through these tubes generating sound vibrations that produce a beautiful sound. The pitch and tone of each note depend on the size and shape of the tube, as well as the strength and frequency of the waves.


The organ spans about 70 meters (230 feet) of shoreline and contains seven groups of sound-producing elements, each made up of several tubes. This arrangement allows for a wide range of notes, creating a complex and ever-changing melody. A musical chord is created as multiple pipes are engaged by the sea water.

The Sound Experience


Visitors to the Sea Organ are treated to a unique experience. The music produced by the movement of the waves in the pipes seems melancholic or meditative. It's a combination of low, rumbling tones and higher whistling sounds that blend together in an unpredictable way.


The sound varies depending on the sea conditions. On calm days, the organ produces a gentle, soothing melody. During rougher weather, as the sea waves become more turbulent, the music becomes more intense, with a wider range of tones and volumes. The movement of the sea determines the musical sounds. This ensures that no two visits to the Sea Organ are exactly alike. You will want to stay on the marble steps so you can hear what the variable force of the waves will do next.

Impact on Zadar


Since its construction, the Sea Organ has had a wonderful impact on Zadar's culture and tourism industry. It has become one of the city's most popular attractions, drawing visitors from around the world who come to experience its unique blend of architecture, music, and natural beauty.


The installation has helped to revitalize the waterfront area, transforming it into a vibrant public space. Locals and tourists gather on the marble steps to listen to the organ's melodies, especially during sunset when the experience is particularly magical. These musical pipes have truly transformed this area of the city. They even won the European prize for urban public space in 2006.


When you are in Zadar, make sure you spend some time relaxing on the white marble steps and taking in the different sounds as the water level rises and falls. It is truly a unique experience and one you will want to savor.
