Ylämaa [ ylæmɑ ː ] was until 2009 an independent municipality in southeastern Finland. It was formed in 1925 from parts of Säkkijärvi, January 1, 2010, the city of Lappeenranta was incorporated. Included the Kirchdorf Lahnajärvi as the administrative center and the surrounding villages Häsälä, Hujakkala, Hyttilä, Ihaksela, Kallola, Lavola Nurmela, Nutikka, Paakkala, Rumpu, Säämälä, Sirkjärvi, Timperilä, Väkevälä, Villala and Ylijärvi to Ylämaa. The municipality had a total area of 408.9 km ² and last 1,408 inhabitants. Well known is the area of their occurrence in rare gemstone Spektrolith.
By 1925 Ylämaa belonged to the municipality Säkkijärvi, today Kondratjewo in the Russian Leningrad Oblast. The name Ylämaa ( Finnish for " human rights") refers to the opposite which is situated on the coast south Säkkijärvis elevated position.
The boundaries of the municipality in 1944 after the defeat of Finland in the Continuation War redefined when Finland ceded a large part of Karelia to the Soviet Union and Ylämaa so became a border community. The new, drawn with a ruler border between the two states was obliquely through the districts of Ylämaa and its neighboring communities Säkkijärvi and Vahviala. Ylämaa even lost a 12 km ² large area of the village Timperilä. Almost all Säkkijärvi and Vahviala (today Jaschino ) the Soviet Union were slammed shut and evacuated the population to Finland. Only the far north of the two municipalities, including the villages Väkevälä and Häsäla, remained in Finland and in 1946 divided between the municipalities Ylämaa Miehikkälä and Lappee.
