Robert Horner

A companion piece to Tacoma, Wash.’s recently opened Center for Urban Waters, which sits in a heavily industrial section of the city, Robert Horner’s Tidal Resonance Chamber offers space to contemplate the effects of modern society on nature. Open to the sky, the chamber’s 8-foot walls surround a platform overlooking a 2,500-gallon inground tank that draws water from, and mirrors the tidal movements of, the nearby Thea Foss Waterway. Because it is the first structure in the city to use rammed-earth construction, the artwork also serves as an example of eco-friendly architectural design.
