The Säimen Mill is located in the village of Säimen in Savonranta. A mill has stood in the same location since 1880. The current mill building, which was operational up until 1960, is from 1937. The Säimen River, which runs next to the mill was harnessed to supply energy to the mill and the electricity-producing generator. The Savonranta Association rented the mill from the municipality to use as a museum in 1978.

The mill building has the majority of the wood machinery and the tools used when doing work at the milk on display. The mill building, which serves as a local heritage museum, also has exhibitions with log-driving, forestry and household artefacts.

In addition to the mill, the museum grounds have other buildings, as well, that have been moved from other parts of Savonranta. A building called Airaan tupa next to the mill depicts the rather modest living arrangements that were normal in the town. The grounds also have a smoke sauna, a smithy with its tools and a stable building that has artefacts related to horses and their uses, to men’s and women’s handicrafts and craftwork and to farming on display. The last building brought to the grounds is a restored milk-collecting platform from the 1950s

Nearby, there is a nature trail with a "laavu", a lean-to style camping shelter
