Cultural landscape changes determined by ethnic changes, domestic and foreign policy of adjoining countries are studied. The goal of the research was to demonstrate how the change in political borders influenced the Karelian Isthmus landscape. During the last one hundred years there have been three main stages in the development of cultural landscapes in the Karelian Isthmus-Finnish, Soviet, and Russian (post-Soviet). The three dominant landscape types (rural; rural-agricultural; collective-garden and recreational) that correspond to the three main stages are considered as are the three subdominant cultural landscape types (military, estate, and countryside).
