Upinniemi

Upinniemi (Obbnäs) is a village in the municipality of Kirkkonummi in southern Finland. It is located approximately 12 km south of the municipal centre.

Upinniemi is dominated by the Finnish naval base, which is one of the largest military installations in the country. The headquarters of the Gulf of Finland Naval Command is also located there. Beginning late in World War II, from 1944 to 1956, the Soviet Union operated the Porkkala Naval Base in this area, under a lease with Finland.
