From the end of World War II until 1956, Soviet Union operated a naval base on the Porkkala peninsula and much of the current Kirkkonummi municipality was part of the base. There are still a couple of landmarks left from the Porkkala parenthesis.
Porkkala Naval Base was a Soviet naval base operational from 1944–1956 in the municipalities of Kirkkonummi, Ingå and Siuntio on the Porkkala peninsula, 30 kilometers (19 mi) west of Helsinki, Finland.
