Nihti

Sörnäinen Harbour (Finnish: Sörnäisten satama, Swedish: Sörnäs hamn) was for nearly one and a half centuries a major harbour and freight terminal in the Port of Helsinki, located in the Sörnäinen district on the eastern shore of the Helsinki city centre area.It was opened in 1863 to serve mainly the country's timber export trade, in 1889 an oil import terminal was added, and more recently containerised cargo and some passenger traffic. The harbour was finally closed down after 145 years of operation in November 2008, when the new Vuosaari Harbour was opened in the eastern suburb, and the facilities moved there. The only remaining functions relate to the adjacent Hanasaari Power Plant, which is itself being gradually decommissioned.The port facilities were connected to the rail network at Pasila station via a branch line called Sörnäinen harbour rail, which originally ran through Vallila, but which in 1965 was re-routed around the inner city area via Kumpula.Since its closure, the harbour area has been redeveloped for residential, retail and leisure use, as part of the Kalasatama development.The harbour was also commonly referred to as 'Sompasaari Harbour', after a small island which originally was located immediately to its south, but which the harbour development had subsumed under reclaimed land.

Sompasaari (Swedish: Sumparn) is an island on the Kruunuvuorenselkä water area in the Sörnäinen district in Helsinki, Finland. On the southern side of the Nihdinkanava channel built in the middle of Sompasaari is the former island of Nihti. The island was originally connected to the continent with reclaimed land and the Sörnäinen Harbour was built on top of it. Because of this, the entire harbour has been referred to as Sompasaari. Signs on roads leading to the harbour used the name Sompasaari exclusively, with an icon representing a cargo harbour. Harbour facilities in Sörnäinen ended in late 2008 when they moved to the new Vuosaari Harbour. In 2016 the island was converted to a residential area and it was separated from nearby Kalasatama by digging a new channel called Sompasaarenkanava between them.

Tervasaari (Swedish: Tjärholmen), meaning "tar island", is an island in Helsinki, Finland, in front of the district of Kruununhaka. Tervasaari is connected to the mainland by a long causeway called Tervasaarenkannas. The causeway is connected to the Pohjoisranta street on the eastern edge of the city centre.Facilities on the island include a granary restaurant, a children's play park, an area for dogs with a dog swimming place, an event venue and a pier for washing mats. Tervasaari was renovated into a functional island in the 1990s.

Suvilahti (Swedish: Södervik) is a former energy production area in Sörnäinen, Helsinki. It encompasses nine buildings and two large gasometers. Construction of a steam turbine electrical power plant was completed in 1909 and a gas plant in 1910. The buildings were constructed using the then revolutionary steel-reinforced concrete method. The architect Selim A. Lindqvist was influenced by Viennese Jugend architecture. The power plant was closed in 1976 and gas production ended in 1994. Since 1 January 2008 the real estate company Kiinteistö Oy Kaapelitalo began developing, renting and maintaining the facilities. The facilities are being renovated for use by artists and other cultural activities. Suvilahti is already home for photography studios, artists, writers, production companies and advertising agencies. The large courtyard is used for outdoor events. Kiinteistö Oy Kaapelitalo is owned by the City of Helsinki. The company is also responsible for the facilities at Kaapelitehdas (Cable Factory) in Ruoholahti, Helsinki.

Hanasaari (Swedish: Hanaholmen) is a neighbourhood in the district of Sörnäinen in Helsinki, Finland, between the neighbourhoods of Vilhonvuori, Kalasatama and Sompasaari near Merihaka. The name comes from an island that was lost under reclaimed land. Hanasaari is primarily a power plant area. The first power plant was built next to Hanasaari in Suvilahti.

Hanasaari Power Plant (also referred as Hanasaari B power plant to distinguish from the dismantled power plant located at the same site) is a coal-fired cogeneration power plant in Sörnäinen, Helsinki, Finland. Its chimney has a height of 150 metres (490 ft).

Tuska Open Air Metal Festival, commonly shortened to Tuska (Finnish: pain, agony), is a Finnish heavy metal festival taking place annually in Helsinki. The first Tuska took place in 1998 and the festival has since grown larger every year. The location of the festival has been in Kaisaniemi park in the middle of the city from 2001. However, since 2011, Tuska has taken place at the Suvilahti event field in the Kalasatama neighbourhood of the Sörnäinen district. The festival dates have always been in either June or July. In recent years the attendance has grown and the festival has drawn up to 43,000 people in 2019. In 2006, the festival was almost sold out and over a combined three-day total of 33,000 attendees arrived to watch 32 artists, including for example Anathema, Celtic Frost, Opeth, Sodom, Venom, and Finland's own Amorphis and Sonata Arctica. There were three stages in Tuska: Inferno, Sue, and the main stage, Radio Rock (Radio City until 2007). In 2019 these three stages are named Inferno, Helsinki and Radio Rock Main Stage.

Mustikkamaa-Korkeasaari (Swedish: Blåbärslandet-Högholmen) is a subdistrict of Helsinki, Finland. It includes the islands of Mustikkamaa and Korkeasaari, as well as some smaller islands. It has a population of 25.

Kalasatama (Swedish: Fiskehamnen; literally translated "fish port") is a neighbourhood in the city of Helsinki, Finland. The area is officially part of the Sörnäinen district; and like Sörnäinen, Kalasatama is located a little more than one kilometre north from the coastal centre of Helsinki, near the district of Hakaniemi, and the east side of Kalasatama borders the sea. Itäväylä, which leads in the direction of East Helsinki, runs next to Kalasatama. The Isoisänsilta pedestrian and cycling bridge, opened in 2016, connects Kalasatama to the nearby islands of Mustikkamaa, Korkeasaari and Kulosaari.Kalasatama is projected to become a rather densely built-up area - about 25,000 inhabitants expected to come there, about as many as in Kallio. In addition, jobs are planned for Kalasatama for about 10,000 people. A concentration of 23- to 35-storey skyscraper towers are coming to the Kalasatama center area around the Kalasatama metro station, which was completed in 2007. Two of the towers, called Majakka and Loisto, and the Redi shopping centre are already completed, while the third tower Lumo One is still under construction. Construction of the third tower, T7, began in the end of 2021.Attempts have been made to build a smart city from Kalasatama that focuses on smart sensors and robotics. Guide robots in the doctors' offices, robot buses and food delivery robots have already been on display in Kalasatama. Formerly there was a cargo harbour in Kalasatama (Sörnäinen harbour) but it was moved to Vuosaari in late 2008. After that the construction of the neighbourhood began.

Sörnäinen (Swedish: Sörnäs; 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.

Isoisänsilta (Swedish: Farfarsbron) is a pedestrian and cycling bridge in Helsinki, Finland, opened in June 2016.The bridge connects the Kalasatama neighbourhood on the Helsinki mainland to the island of Mustikkamaa and, via it, to the islands of Korkeasaari and Kulosaari.The total length of the bridge is c. 170 metres (560 ft), including the 144 metres (472 ft) main span. The minimum width of the deck is 4 metres (13 ft), which at the Kalasatama end widens and splits into two lanes separated by the central bridge arch. Conversely, at the Mustikkamaa end, the arch splits into two supports on either side of the central bridge deck. The bridge was designed by the civil engineering firm Pontek, and is based on their winning entry, titled Tiikerihai ("Tiger Shark"), into the design contest held by the City of Helsinki in 2011. Construction began in 2014 and was completed in 2016, with the bridge opening to traffic on 1 June 2016.The bridge is named after the Isoisänniemi promontory of Mustikkamaa, and its name literally translates as "Grandfather's Bridge".Some locals have taken to climbing on top of the bridge arch, in a number cases jumping off into the sea approximately 14 metres (46 ft) below, which the police and rescue service strongly advice against as dangerous.In 2017, the Finnish Association of Civil Engineers chose Isoisänsilta as the 'Bridge of the Year'.

Kalasatama metro station (Finnish: Kalasataman metroasema, Swedish: Fiskehamnens metrostation - "Fish Harbor") is a ground-level station on the Helsinki Metro, in the capital city of Finland. The station was opened on 1 January 2007, and it serves the eastern part of the central Helsinki district of Sörnäinen's quarter Kalasatama. The area is mainly composed of offices and apartments, with new residential and commercial developments being under construction in the area, including the shopping center Redi. The port facilities previously in the area were moved to Vuosaari Harbour in 2008. Unlike most other stations on the Helsinki Metro, Kalasatama was built while the metro was still running, which made construction difficult. Despite this, service was not greatly affected on either of the lines during the station's construction. Because the new platforms were built on either side of the existing metro track, Kalasatama is one of only two stations on the Helsinki Metro to have two separate side platforms. The other example of this layout on the Helsinki Metro is Itäkeskus metro station. Other metro stations have only singular island platforms. Kalasatama metro station is located 1.1 kilometres from Sörnäinen metro station, and 1.8 kilometres from Kulosaari metro station.
