A world-class facility inside and out, Tamástslikt is the only museum on the Oregon Trail that tells the story of western expansionism from a tribal point of view. But the museum doesn’t merely remember what has been. Tamástslikt (the word means “interpreter”) connects this rich, storied history to our present day–did you know, for example, that the confederated tribes are recognized leaders in the restoration of salmon habitats?–and then expands the experience further by sharing the dreams and concerns of its tribal community in a moving exhibit called “We Will Be.” Learn more by watching this short video.

We invite you to immerse yourself in the history, culture, and hospitality of the people who have lived on this land for more than 16,000 years. Tamástslikt celebrates the customs and practices of the Cayuse, Umatilla, and Walla Walla Tribes through interactive displays, special events, and informative programming. You’ll discover that despite the onslaught of immigrants and ensuing disruption, war, forced treaties, boarding schools, and parceling away of reservation land, a vibrant community  thrives today.

We welcomed our earliest visitors, and we continue to welcome you today.


Tamastslikt Cultural Institute is committed to reaching net zero energy consumption.

Toward that end, a wind turbine was installed in 2014 with anticipated savings of $480,000 in 30 years.

In 2016, 432 SolarWorld 285-watt solar panels were installed in the carport which produces about 140,000kW hours of electricity per year – enough to power thirteen average Northwest homes.


We will periodically connect you to videos and podcasts that provide compelling and inspirational information about the Cayuse, Umatilla, and Walla Walla Tribes and news about Tamastslikt Cultural Institute.
