Our History

The MonDak Heritage Center is Eastern Montana’s premier museum and the arts & cultural hub of Richland County, Montana. Operated by the MonDak Historical & Art Society, we are a 501(c)(3) non-profit organization with a mission is to engage, educate, and inspire our community by preserving and contributing to the area’s arts, culture, and heritage.

Local residents formed the Society in 1967 and opened a temporary museum known as the J.K. Ralston Museum and Art Center in 1972 in the “old hospital” in Sidney, Montana. Named after Ralston, the famed western artist and Richland County native, the Ralston Center operated for twelve years until the museum moved to the MonDak Heritage Center in 1984.
