Sörnäinen (; Sörkkä or Sörkka in Helsinki slang) is a neighbourhood in the city of Helsinki, Finland. Sörnäinen is located a little more than one kilometre north from the coastal centre of Helsinki, near the district of Hakaniemi. The east side of Sörnäinen borders the sea. Sörnäinen used to be primarily an industrial district with many shipping companies and warehouses, however, nowadays it is a thriving urban area divided into four districts: Vilhonvuori, Kalasatama, Sompasaari and Hanasaari. It also has two metro stations: Sörnäinen metro station and Kalasatama metro station in the Kalasatama quarter. The headquarters of Senate Properties (Senaatti-kiinteistöt) is located in Sörnäinen. Also the Helsinki Prison located there. Etymology The name "Sörnäinen" comes from the Swedish name "Södernäs" ("Southern cape") and was first mentioned in the foundation document for the New Helsinki in 1639, although the name is probably much older. At the time, there were plans to relocate the city to the area of present-day Sörnäinen. In the end, the city was relocated to Vironniemi instead. Already in the 18th century the name Södernäs had changed to the dialectical form Sörnäs on maps. In Finnish, the name was first used as "Sörnäsi" in the late 19th century and then as "Söörnäinen" in the early 20th century. In 1928 it was officially established as Sörnäinen - Sörnäs. In Helsinki slang the area is known by the names Sörkka and Sörkkä. These names probably come from the Swedish language slang name Sörckan. History Birth of the harbour In the early 19th century the area of present-day Sörnäinen consisted of countryside, although there was already a brick factory in Lintulahti at the time. Sörnäinen began to industrialise in 1825, when the city ordered factories and workspaces to be located on the edges of the city because of danger of fires. Building the street Itäinen Viertotie (now known as Hämeentie) from Siltasaari to Kumpula in the 1850s was important for the development of the eastern part of the city proper. Factories rose on the eastern side of the street and residential buildings on the western side. The largest continuous industrial area formed on the Sörnäinen shore when the Sörnäinen harbour was built there. Finland's first harbour track, the Sörnäinen harbour rail, was built in 1863. The track led from Pasila to the Sörnäinen harbour along Teollisuuskatu. This started the rapid growth of Sörnäinen. The harbour was expanded by the growth of
