A Sound Garden is an outdoor public art work in Seattle, Washington, United States. It is one of six such works on the National Oceanic and Atmospheric Administration (NOAA) campus, which lies adjacent to Warren G. Magnuson Park on the northwestern shore of Lake Washington. Designed and built by sculptor Douglas Hollis from 1982 to 1983, the sound sculpture is composed of twelve 21-foot high steel tower structures, at the top of each of which hangs an organ pipe attached to a weather vane that produces soft-toned sounds when stirred by the wind.
