What) Perched on a hilltop in a South San Francisco industrial park, this striking 92-foot-tall sculpture by Aristides Demetrios is one of the world's largest aeolian harps. Named for Aeolus, the Greek god of the wind, and invented by the 17th-century polymath Athanasius Kircher, an aeolian harp is a passive instrument played by the movement of the wind.  Be sure to visit on a breezy day to hear the eerie sounds of the arched and rusted steel I-beams singing at their loudest. Situated 243 feet above sea level, the site also offers a beautiful panoramic view of South San Francisco and the Bay. (1)

    Where) Grandview Drive, 1227 Masonic Ave #9, South San Francisco

    Why) I didn't even know about this place until after we got back from our trip.  The pictures I saw were beautiful though so I thought I would include it here anyway.  Perhaps some day in the future I will even get to hear it play.
