2 Best Sights in Northern Dalmatia, Croatia

The whimsically named The Greeting to the Sun is a 22-meter circle of multilayered glass plates set into the stone-paved waterfront. Under the glass, light-sensitive solar modules soak up the sun's energy during daylight hours, turning it into electrical energy. Just after sunset, it puts on an impressive light show, illuminating the waterfront in shades of blue, green, red, and yellow. It was installed in 2008 and was created by local architect Nikola Bašić, who also made the nearby sound art project, the Sea Organ.

Comprising 35 pipes under the quay stretching along a 230-foot stretch of Zadar's atmospheric Riva promenade, the Sea Organ yields a never-ending concert that delights one and all. Designed by architect Nikola Bašić with the help of other experts, the organ's sound resembles a whale song, but it is, in fact, the sea itself. It's hard not to be in awe as the sound of the sea undulates in rhythm and volume with the waves.
