Yakima Valley SunDome

The Yakima Valley SunDome is a 6,195-seat multi-purpose arena in Yakima, Washington, United States. Located on the Central Washington State Fairgrounds, it hosts sporting events, ice shows, horse shows, circuses, boxing and concerts, as well as trade shows and conventions. The stadium opened on January 16, 1990, and cost $14.8 million to construct. The building was designed by architecture firm Loofburrow & Associates.

The building features a 90-foot (27 m) dome and was the second in the world to use a concrete sectional roof design (24 segments), the first being Seattle's Kingdome. It has 56,000 square feet (5,200 m) of space and can accommodate two basketball courts laid end-to-end. The SunDome initially had 5,200 permanent seats with expanded capacity of up to 8,000 for concerts.
