Pörtom (Finnish: Pirttikylä) is a former municipality in Ostrobothnia, Finland.[1] The municipality was consolidated with Närpes in 1973.[1] [2] North Pörtom, however, was transferred to Malax in 1975.[3]
The municipality was mostly Swedish-speaking.
Pörtom was first mentioned as Pörttom, Pörteby in 1558. The name Pörtom is the old dative case form of the word pörte, a loanword from Finnish pirtti referring to a type of cottage. The village was also known as Pirttilä in Finnish.[4]
Pörtom was initially a part of the Närpes parish. Pörtom acquired its first church in 1696 and a priest in 1702. It became a separate parish in 1859, remaining separate until it was transferred back to Närpes in 1973.[5]
The Berga glass factory was active in Pörtom between 1796 and 1883. It was one of Finland's largest glass factories in the 1840s.[6]
