'''Lauttasaari''' ({{IPA|fi|ˈlɑu̯tːɑˌsɑːri|lang}}; {{langx|sv|Drumsö}}) is an island in [[Helsinki]], [[Finland]], about {{convert|3|km}} west of the city centre. Together with some surrounding unpopulated small islands, Lauttasaari is also a [[Subdivisions of Helsinki#Districts|district]] of Helsinki. With 23,226 residents as of 2017,<ref name="syh2017">{{cite web | url=https://www.hel.fi/hel2/tietokeskus/julkaisut/pdf/18_01_02_tilastollinen_vuosikirja2017.pdf | title=Statistical yearbook of Helsinki 2017 | year=2017 | publisher=City of Helsinki | format=PDF | access-date=13 January 2018}}</ref> the island is Finland's second largest by population, after [[Fasta Åland]]. Its land area is 3.85&nbsp;km{{sup|2}}.

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 colonisation of Finland|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''.<ref>Kepsu, Saulo: ''Uuteen maahan - Helsingin ja Vantaan vanha asutus ja nimistö'', [[Finnish Literature Society]] 2005, pp. 80-82. {{ISBN|978-951-7-46723-0}}.</ref>

The name of the island is first mentioned in {{start date and age|1540|p=y}} as ''Drommensöö'', in 1543 as ''Drommensby'' and in 1556 as ''Dromansöö'' and ''Dromssöö'', which has led to its current name ''Drumsö''.<ref name="terho">Terho, Olavi ''et al.'': ''[https://www.hel.fi/static/tieke/digitoidut_asiakirjat/helsingin_kadunnimien_historia/pdf/Helsingin_kadunnimet_1.pdf Helsingin kadunnimet 1]'', 2nd revised edition, p. 19. Naming bureau of the city of Helsinki 1981, {{ISBN|951-771-220-0}}. Accessed on 20 May 2015.</ref> The name has traditionally been seen as coming from the [[Swedish language]] nickname ''Drumber'' meaning a fat and clumsy person.<ref name="terho"/>

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 [[Viking]]s on the shores of Finland.<ref>Sarmanto, Terhi: [http://hdl.handle.net/10138/232445 Lauttasaaren vuoden 1913 asemakaavaluonnoksen nimistö]. Master's thesis, [[University of Helsinki]] 2017.</ref>

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.<ref name="terho"/> 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]].<ref>Elomaa, Ville: ''Lauttasaaren lautta aloitti liikenteensä sata vuotta sitten.''

== History ==
[[File:Mutterikahvila.jpg|thumb|right|300px|Mutteri café in Lauttasaari.]]
There used to be two farms in Lauttasaari, Heikas and Bertas. In 1650 [[Christina, Queen of Sweden|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.<ref name="uino">Uino, Ari: ''Lauttasaaren historiallisia vaiheita Julius Tallbergin ajasta 2000-luvulle''. Lauttasaari foundation, 2005. {{ISBN|952-91-9261-4}}.</ref>{{rp|15}}

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.<ref name="brommels">Brommels, Marianne; Gestrin, Christine-Louise: ''Lauttasaari ennen siltaa. (Drumsö: Innan bron byggdes.)'' Translated to Finnish by Marjo Uusikylä. Svenska kulturfonden, 1999. {{ISBN|951-9211-44-6}}.</ref>{{rp|21–22}} 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.<ref name="uino"/>{{rp|25}}

During the [[Winter War]] and the [[Continuation War]] an anti-aircraft battery against the [[bombing of Helsinki in World War II|bombing of Helsinki]] was situated on Myllykallio in Lauttasaari. During the Continuation War the battery was armed with six heavy anti-aircraft cannons. One of these cannons was revealed as a memorial monument on Myllykallio on 12 June 1980. The leading battery of the southwestern sector was located in Veijarivuorenniemi in Lauttasaari, of which one cannon has been preserved on site as a memorial monument.{{citation needed|date=July 2022}}

=== Julius Tallberg era and early building plans ===
The pace of the development of Lauttasaari has been set by traffic connections. In the early 20th century the island was only inhabited by farms and villas.<ref name="brommels"/>{{rp|28}} In 1911 [[Julius Tallberg]] bought the Lauttasaari manor for 750 thousand [[Finnish markka]], whose lands covered about half of the island. Tallberg tried to sell the lands to the city of Helsinki, but as the city did not expect its lands to spread to the island, the deal failed.<ref name="brommels"/>{{rp|24–26}} Tallberg started developing the island by himself and hired [[Birger Brunila]] to make a building plan. According to the plan, the island would be mostly built as a villa town, but it took over 20 years before this plan was put to action. Tallberg founded a marine spa and a café named ''[[Drumsö Casino]]'' on the island.<ref name="brommels"/>{{rp|53}} From 1913 to 1917 the island was also served by a horse-drawn [[tram]], trafficking from the ferry pier at the start of the current Lauttasaarentie street to Katajaharjunniemi.<ref>Rauhala, Jorma: [https://www.raitio.org/wp-content/uploads/2018/04/SRS_Lauttasaaren_hevosraitiotie.pdf Lauttasaaren hevostaitiotie], Finnish Tram Society. Accessed on 14 January 2019.</ref>

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]].<ref>Hietala, Marjatta; Helminen, Martti; Schulman, Harry; Tukkimäki, Jukka: ''Helsinki/Helsingfors – Historiallinen kaupunkikartasto/Historic Town Atlas'', information centre of the city of Helsinki 2009, p. 61 (map). {{ISBN|978-952-223-330-1}}.</ref> Nothing ever became of this plan.

=== Municipal history ===
In 1919 Lauttasaari and Munkkiniemi were separated from the [[Vantaa|rural municipality of Helsinki]] to form the municipality of [[Huopalahti]] (Hoplax). In 1917 Lauttasaari had been formed as a tightly populated community.<ref name="mustonen">Mustonen, Kauko; Pykälä, Kalevi: ''Lauttasaari: helmi Helsingin kruunussa''. Lauttasaaren kustannus, 1976.</ref>{{rp|43}} Together with the rest of Huopalahti, Lauttasaari was annexed to the city of Helsinki on 1 January 1946.<ref name="mustonen"/>{{rp|13}} 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<ref name="mustonen"/>{{rp|48}} 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,<ref name="uino"/>{{rp|21}} 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 ==
=== Vattuniemi ===
Vattuniemi is an area in the southern part of the island of Lauttasaari. Vattuniemi was built in the 1940s and 1950s as an industrial area,<ref name="mustonen"/>{{rp|193}} with diverse corporate activity such as the factory of Suomen Tupakka ("Finnish Tobacco") which ceased activities in 1995.<ref>[https://www.porssitieto.fi/osake/lisaa/stupakka-uusi.shtml Suomen Tupakka Oy (uusi) — Historia], www.porssitieto.fi. Accessed on 13 January 2019.</ref> Other former factories in the area include the Hellberg radio factory (Oy Radio E Hellberg Ab), the [[wood veneer]] factory of [[Mahogany Oy]]<ref name="elomaa">Elomaa, Ville: Kun Vattuniemi asuinalueeksi muuttui. ''Lauttasaari'' magazine 10 January 2019, issue #2, p. 8.

Accessed on 13 January 2019.</ref> The area has also included the head offices of [[Helkama]] and [[Lääketukku]].<ref name="elomaa"/>

There are still numerous businesses in the Vattuniemi industrial area, such as [[Solar Films]]. Since the 1970s the Vattuniemi area has changed significantly. The change has continued strongly in the 21st century. Many industrial and office buildings in the area have been dismantled and replaced with apartment buildings. This has caused the population of Vattuniemi to quickly increase, and the number of jobs to decrease. The selection of services in the area has grown, and it includes grocery stores ([[S-Market]], [[K-Supermarket]], [[Lidl]]), numerous [[restaurant]]s, [[café]]s, [[health club]]s and specialist stores concentrating on boating supplies especially along the street Veneentekijäntie.<ref>[https://www.google.com/maps/place/B%C3%A5tbyggarv%C3%A4gen,+00210+Helsingfors,+Finland/@60.1508187,24.8857303,17z/data=!3m1!4b1!4m5!3m4!1s0x46920a584cfc5f0b:0xc6656f91aa59306!8m2!3d60.1508187!4d24.887919 Veneentekijäntie], [[Google Maps]].

Of the inhabitants in Lauttasaari, 79.0% are [[Finnish language|Finnish]]-speaking, 13.6% are [[Swedish language|Swedish]]-speaking and 7.4% speak another language. Of the population over 25 years old 70.6% have a higher education diploma (as of 31 December 2018).<ref name="tikkanen">Tikkanen, Tea: ''[https://www.hel.fi/hel2/tietokeskus/julkaisut/pdf/20_06_10_Hki_Alueittain_2019_Tikkanen.pdf Helsinki alueittain 2019]'', city of Helsinki, p. 52. {{ISSN|2323-4547}}.</ref>

=== Connection to the mainland ===
There are two bridges connecting Lauttasaari to mainland Helsinki. The [[Lauttasaari bridge]] leads from [[Ruoholahti]] to Lauttasaarentie, and the [[Lapinlahti bridge]] is part of the [[Länsiväylä]] highway leading west from Helsinki, located to the north of the Lauttasaari bridge and built in the 1960s. Upon completion the Lapinlahti bridge was the longest bridge in Helsinki at the time. Before the Länsiväylä highway was built the street Lauttasaarentie was part of the main road leading west from Helsinki. The street Jorvaksentie, the predecessor of Länsiväylä, started from its western end.

In the 1950s the original Lauttasaari bridge from 1935 was seen as far too narrow, and it was dismantled in 1967, two years after the highway bridge to the north of it had been completed. The current four-lane Lauttasaari bridge was built in place of the dismantled bridge.<ref name="mustonen"/>{{rp|48–52}}

=== Public transport ===
==== Metro ====
[[File:Lauttasaari metro station (Nov 2017).jpg|thumb|right|[[Lauttasaari metro station]]]]
The [[Helsinki metro]] has two stations in the district, the [[Lauttasaari metro station|Lauttasaari]] and the [[Koivusaari metro station|Koivusaari]] stations. The Lauttasaari metro station is served by two entrances: one in the [[Lauttis]] shopping centre, and one on Gyldenintie.

==== Bus ====
All the internal bus routes — 20, 21, and 21B — connect with at least one of the metro stations, and the routes 20 and 21 continue to the city centre. The bus routes 115A and 555 start at the centre of the island. Route 115A runs via [[Tapiola]] to [[Mankkaa]] in Espoo, and route 555 runs via Espoo to [[Martinlaakso]] in the city of [[Vantaa]]. Lauttasaari is also served by night bus routes 20N and 112N from the city centre.

=== Car ===
The [[Länsiväylä]] (also the [[Finnish national road 51|National road 51]]) motorway that links central Helsinki with Espoo passes through Lauttasaari, and has two interchanges on the island. Espoo's side starts in the [[Westend, Espoo|Westend district]]. Going towards the city center of Helsinki, the Länsiväylä will run along the [[Lauttasaari Bridge]], which was built in late December 1969.<ref>Kauko Mustonen, Kalevi Pykälä: ''Lauttasaari : helmi Helsingin kruunussa'', pp. 48–52.

== Organisational activity ==
Lauttasaari is an organisationally active district. This is evident from the influential, politically independent local [[Lauttasaari Society]].

A local voluntary fire brigade was founded in 1916 by the initiative of postman [[Emil Wathén]]<ref name="karhiaho">Karhiaho, Irmeli: ''Palokunta-aate yhdisti saarelaiset.'' ''Lauttasaari'' magazine 5 May 2011, issue #18.</ref> with financial support from [[Julius Tallberg]], for which Tallberg donated the building lot and building supplies for its own fire brigade house.<ref name="mustonen"/>{{rp|193}} This classic wooden fire brigade house with a hose tower was in service until 1965 when it was dismantled and was replaced with the current fire brigade house built from stone.

A noteworthy aspect of the fire brigade's history is that the artist [[Ola Fogelberg]], nicknamed "Fogeli", living in Lauttasaari served as its chief for several years. His portrait still remains on the wall of the fire brigade house along with the portraits of other chiefs and honorary members. His term as chief ended at the start of the [[Winter War]].<ref name="karhiaho"/>

===The hunt of "Nastamuumio"===
For a couple of decades, an unknown person has been causing trouble for cyclists on Lauttasaari by sprinkling [[Drawing pin|thumb tacks]] on the street, whom the media calls the "Nastamuumio" ({{literal|Tack Mummy}}, a pun on "Mustanaamio" ({{literal|Black Mask}}), the Finnish name for the comics character [[The Phantom]]).<ref name="nastamuumio"/> Attempts have been made to solve the case, even using a [[private investigator]], but with poor results.<ref>{{cite web|url=https://www.hs.fi/helsinki/art-2000009649642.html|title=Nastamuumion jäljillä|trans-title=On the trail of the "Nastamuumio"|first=Vilma|last=Ikola|work=[[Helsingin Sanomat]]|date=9 July 2023|access-date=17 May 2025|language=fi|url-access=subscription}}</ref> Information from the public is still being sought to track down the "Nastamuumio".<ref name="nastamuumio">{{cite web|url=https://www.hs.fi/helsinki/art-2000011230078.html|title="Nastamuumio" kylvää taas nastoja Lauttasaaressa|trans-title=The "Nastamuumio" is sprinkling tacks again in Lauttasaari|first=Pipsa|last=Sinkko-Westerholm|work=[[Helsingin Sanomat]]|date=15 May 2025|access-date=17 May 2025|language=fi}}</ref>

== Future ==
The population of Lauttasaari at the end of the 2020s was estimated to be 24,797 inhabitants.<ref>Vuori, Pekka; Kaasila, Marjo: ''[https://www.hel.fi/hel2/tietokeskus/julkaisut/pdf/20_11_04_Tilastoja_11_Vuori_Kaasila.pdf Helsingin ja Helsingin seudun väestöennuste 2019–2060]'', city of Helsinki 2020, p. 66.</ref>

The amount of traffic in Lauttasaari is going to increase, as the number of visitors to the [[Lauttasaari metro station]] and the [[Koivusaari metro station]] are projected to reach 30 thousand people per day in total.{{citation needed|date=July 2022}}

== Subdistricts ==
[[File:Houses above the sea in Lauttasaari.jpg|thumb|right|Apartment houses built partially above the sea on the southern shore of Lauttasaari.]]
The district of Lauttasaari is divided into four subdistricts.<ref name="syh2017"/>

=== Koivusaari ===
The subdistrict of [[Koivusaari]] is a separate island, separated from Lauttasaari by a narrow channel. It had no residents as of 2017.<ref name="syh2017"/> Its postal code is 00200. The [[Koivusaari metro station]] was built in anticipation of extending the island by land fill and constructing residential buildings on it.
