The Singing Skyscraper

When a strong, stable wind is blowing, the Kista Science Tower is singing with clear and intense tones. The pitch is approx. f1 and f2 (349 and 698 Hz). The source of the mystic sound has not known yet been located. We are waiting for the right wind; occurs normally a couple of times a year.
