Fodor's Expert Review 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 (and ever free) 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.
