There used to be two farms in Lauttasaari, Heikas and Bertas. In 1650
Queen Christina donated the island to the city of Helsinki, but this donation was revoked during the
Great Reduction and the farms were returned to private ownership. They were later combined into the
Lauttasaari manor, whose current main building was commissioned by
Claes Wilhelm Gyldén in 1837. The southernmost part of Lauttasaari was taken into the use of the Russian military during the
Crimean War. No garrison was founded in Lauttasaari, but fortifications and ammunition depots of the coastal artillery were built on the island. After Finland became independent the areas was owned by the state of Finland, but as the Finnish Defence Forces had no use for the area, in 1927 it was transferred to the city of Helsinki, which founded a
folkpark in the area. According to
Eliel Saarinen's 1918
Pro Helsingfors plan a large part of Lauttasaari would be designated as a harbour area, with a train connection from the
Leppävaara railway station at the current sites of
Ring I and
Länsiväylä. Nothing ever became of this plan.
Municipal history In 1919 Lauttasaari and Munkkiniemi were separated from the
rural municipality of Helsinki to form the municipality of
Huopalahti (Hoplax). In 1917 Lauttasaari had been formed as a tightly populated community. Together with the rest of Huopalahti, Lauttasaari was annexed to the city of Helsinki on 1 January 1946. The congregation of Lauttasaari had been annexed to Helsinki already a few years earlier, to the northern Finnish-speaking and the northern Swedish-speaking congregations in Helsinki in 1939.
The significance of the Lauttasaari bridge to the development of the island When the Lauttasaari bridge was completed in 1935 the island underwent great changes. Birger Brunila's 1913 plan was finally put the action and the first apartment buildings were built on the fields of the manor. At the same time, a new main street Jorvaksentie was built as a westward extension of the main street Lauttasaarentie running all the way through the island. The current zoning plan of the island is mostly based on Brunila's original plan, although a few of the building blocks designed at the time have been left as parks, and the construction of the
Länsiväylä highway has required significant changes to the zoning plans of the western and northern parts of the island. == Largest peninsulas ==
