Tamástslikt Cultural Institute
Located at the Wildhorse Resort and Casino, this impressive 45,000-square-foot interpretive center depicts history from the perspective of the Cayuse, Umatilla, and Walla Walla tribes (Tamástslikt means "interpret" in the Walla Walla native language). An art gallery showcases the work of local and regional tribal artists, and on Saturday in summer you can visit the adjacent Living Culture Village, Naami Nishaycht, and watch a variety of talks and demonstrations on everything from tepee building to traditional community games. There's also a museum gift shop, a theater showing a short film about the tribe's heritage, and a café.
