Where the Sonics played through the years.
Seattle Center Coliseum
The Sonics’ first home was built in 1962 for the World’s Fair. It was called the Washington State Pavilion then, and was host to displays of what life would be like in the 21st century. After the fair, the building was remodeled as a basketball arena and opened as the Seattle Center Coliseum in 1964.
The Sonics played their first 11 seasons there, then after seven years at the Kingdome, returned for nine more years. Capacity for the Coliseum was listed as 12,595 for 1967-68, and the Sonics averaged 6,186 their first season.
