The story
The municipality of Ruovesi is named after the eponymous lake, whose name may have originally been *Ruokovesi, derived from the word ruoko meaning 'reed'. The parish of Ruovesi was separated from Pirkkala in 1565, and included the territories of later Ähtäri, Keuruu, Kuru, Mänttä, Multia, Pihlajavesi, Pohjaslahti, Vilppula and Virrat at that time.
