The sea organ lies at the northern end of the Riva, beneath a set of large steps and creates a strange music. Beneath your feet, 35 pipes are arranged at the surface of the water and react to the movement of the sea, creating different sounds depending on the wave. A spellbinding place, where you can relax and chat or just let your thoughts wander. Nearby, the Greeting to the Sun, another work by Nikola Bašic, is a 22m-diameter circle of almost 300 solar panels that produce 46 500kW a year.
