The Museum of the Home Mission Society is located on the campus of the Home Mission Society near downtown Pieksämäki. The oldest parts of the colleges (the main building, the buildings of the former children’s home and retirement centre and the hospital) were built at the beginning of the 1950s to meet the needs of the society, which had moved from Sortavala to Pieksämäki. Nowadays, the museum is owned by the Church Resources Agency and has just received new, remodelled facilities in the main building of the college in 2007. The college's former employees are responsible for tours and the museum’s opening hours.

Volunteers were responsible for establishing the Museum of the Home Mission Society and gathering the collections. Lecturer Katri Kuittinen and the museum committee that supported her gathered and recorded the furniture, items, books and photographs found at the college and the Koivuranta service centre. In addition, many of the former nursing students and employees donated items that had to the museum. More than 500 items were added to the collections and the museum was opened to the public in 1989.
