The toponym kannonn Maa [sic] was mentioned in 1552, referring to hunting grounds of the people of Sysmä in this area.

By 1558 the area had got permanent Savonian settlers, who established the village of Kantojärvi (transcribed as Kandoijerffuij).

The monks lived in the Piispala school, which at the time was closed due to the ongoing war.

The monks left Kannonkoski in the autumn of 1940 after they had purchased an old manor in Heinävesi, where the New Valamo monastery was soon established.

[6] Kannonkoski, Karstula, Kivijärvi and Kyyjärvi planned to merge into the Suomenselkä municipality [fi] from January 1, 2022.
