Yakima SunDome

Yakima SunDome is a multipurpose arena with around 56,000 square feet of space that houses two basketball courts positioned end-to-end. The facility hosts a range of indoor sporting competitions and events.

The structure was built in 1990 following a successful vote in 1985, after an earlier funding attempt failed in the early 1980s. It became a key addition to the city's public facilities.

The Circle of Light display on the exterior features reflective tiles that reference traditional Yakama basket patterns. This installation bridges regional heritage with modern architecture.

The arena offers flexible seating arrangements that vary depending on the type of event. Capacity ranges from around 5,600 seats for sports competitions to about 7,900 for concerts and large events.

The building was one of the first worldwide to use a roof system made from prefabricated concrete sections. This innovative design approach influenced construction methods at other major arenas later.
