The Marion Oliver McCaw Hall is a performance hall and opera house located in Seattle, Washington. Inaugurated in June 2003, it was constructed within the basic steel support structure of the earlier Seattle Opera House, originally created for the World's Fair in 1962 and gutted for this reconstruction. McCaw Hall is owned by the city of Seattle. Its two major tenants are the Seattle Opera and the Pacific Northwest Ballet. The adjacent Kreielsheimer Promenade, designed by Gustafson Guthrie Nichol, is a dramatic and unique meeting place for patrons and visitors to McCaw Hall that also creates a welcoming public passage into the heart of the Seattle Center Campus. An extraordinary collaboration between disciplines can be seen in the landscape’s elegant integration of architecture, landscape, lighting, and theater. Though it is not apparent from looking at the finished landscape, a portion of the Promenade is a rooftop plaza, built over mechanical rooms below. Within the Promenade, a series of glowing, transparent scrims float overhead and appear to continue into the interior Lobby. This art installation, created by New York light artist Leni Schwendinger , is entitled Dreaming in Color . Three large, thin sheets of water shimmer over sloped paving in the center portion of the Promenade. Gustafson Guthrie Nichol designed the water feature to reflect the sky, the metal scrims and lighting effects at night. The building architects were LMN Architects.
