Another wacky and wonderful creation by Nikola Bašić (the local architect who designed the nearby Sea Organ), this 22m-wide circle set into the pavement is filled with 300 multilayered glass plates that collect the sun’s energy during the day. Together with the wave energy that makes the Sea Organ’s sound, it produces a trippy light show from sunset to sunrise that’s meant to simulate the solar system. It also collects enough energy to power the entire harbour-front lighting system.

　　The place is packed with tourists, excited children and locals every night, especially at sunset, when the gorgeous sea views and the illuminated pavement make for a spectacular sight.
