Seattle Center Coliseum

The arena began life in 1962 as the Washington State Pavilion for the Century 21 Exposition, the work of architect Paul Thiry. After the close of the Exposition the Pavilion was remodeled as the Washington State Coliseum, one of the centerpieces of the new Seattle Center (the former Exposition grounds). When the newly renovated Coliseum opened the Seattle University men's basketball team became the arena's first major tenant. The Coliseum became home to the Seattle SuperSonics beginning with their inaugural season in 1967 and remained so throughout most of the team's lifetime. The Washington State Coliseum would later be renamed the Seattle Center Coliseum; operated by the City of Seattle and named after the Seattle Center grounds. A multi-purpose indoor arena located in Seattle, Washington, USA.
