The Heinävesi Museum is situated on the church hill, next to the church and near downtown Heinävesi. The museum building is a former granary. The building’s longer wing is from the beginning of the 19th century and the expansion from 1900. The museum was founded by the Heinävesi Association and was opened to the public in 1961. Since 2002, the municipality of Heinävesi has been responsible for the museum and for running it.

The exhibition, which is grouped into themes, is located on the top floor of the building. The history of Heinävesi and its residents is on display, starting with the Pit-Comb Ware period from up to 5,000 years ago. The museum has a sizeable collection of tools for farming, hunting and fishing, as well as products made by local artisans and craftspeople. The exhibition also has artefacts related to the original activities of the museum building, i.e., when it was still a granary.

Across from the museum is the former parish hall, which was built in 1852 and was used for town meetings, as a gaol, a telephone exchange, a mother and child health care centre, a savings bank, a post office and an upper elementary school.  The building housed a handicraft information centre from 1973 to 2005.  Currently, the house is used by local weavers and a 4H club. The museum room in Heinävesi Church is also quite nearby.
