Liljendal was originally the name of a seat farm (säteri) in the village of Sävträsk. Its name may have been derived from that of an old Cistercian monastery in Lower Saxony, Lilienthal. At the time, it was a part of the Pernå (Pernaja) parish. The name got its current meaning when the seat farm and nine villages near it became their own chapel community in 1791.[5] Liljendal became a separate parish in 1914.[6]
