Lauttasaari (; ) is an island in Helsinki, Finland, about west of the city centre. Together with some surrounding unpopulated small islands, Lauttasaari is also a district of Helsinki. With 23,226 residents as of 2017, the island is Finland's second largest by population, after Fasta Åland. Its land area is 3.85 km. Lauttasaari is primarily a residential area but also contains services, including several marinas and canoe clubs. Although close to the city centre, Lauttasaari has not been entirely built up. Notably, almost the entire shoreline remains in public use, with footpaths, beaches, playgrounds, patches of forest, and rocky outcrops. The name Lauttasaari literally means "ferry island", although nowadays, the island is connected to the rest of Helsinki and to the city of Espoo by bridges, causeways, and the Helsinki metro, which has two stations in the district. The island has two postal codes: 00200 and 00210. Etymology The island of Lauttasaari has probably been a recreational area for the Finns even before the Middle Ages and it has had a Finnish name. This name was abandoned when a Swedish colonist built a house on the island. Some of the Swedish place names have preserved original Finnish place names, such as Lemisholm and Porovik. The name of the island is first mentioned in as Drommensöö, in 1543 as Drommensby and in 1556 as Dromansöö and Dromssöö, which has led to its current name Drumsö. The name has traditionally been seen as coming from the Swedish language nickname Drumber meaning a fat and clumsy person. In the 2000s it was proposed that the name is based on the Gaelic-Saxon word drum meaning a moraine hill (cf. the geological term drumlin). Thus the name would come from the Vikings on the shores of Finland. The Finnish name Lauttasaari was taken into use in 1919 and refers to the ferry traffic between the island and mainland Helsinki at the time. The steam ferry Drumsö owned by Julius Tallberg was in traffic between Ruoholahti and Lauttasaari from 1914 to 1936. After the bridge was completed the ferry was lengthened at a dock, and in 1941 it was transferred to a new service as a Korkeasaari ferry. In 1945 the ship was donated as war reparations to the Soviet Union. History There used to be two farms in Lauttasaari, Heikas and Bertas. In 1650 Queen Christina donated the island to the city of Helsinki, but
