Helsinki

The origin of the name is uncertain. According to a theory put forward in the 1630s, at the time of Swedish colonisation of the Finnish coast, colonists from Hälsingland in central Sweden arrived at what is now the Vantaa River and called it Helsingå ('Helsinge River'), giving rise to the names of the village and church of Helsinge in the 1300s. This theory is questionable, as dialect research suggests that the settlers came from Uppland and the surrounding areas. Others have suggested that the name derives from the Swedish word helsing, an archaic form of the word hals ('neck'), which refers to the narrowest part of a river, the rapids. Other Scandinavian towns in similar geographical locations were given similar names at the time, such as Helsingør in Denmark and Helsingborg in Sweden. …

After the end of the Ice Age and the retreat of the ice sheet, the first settlers arrived in the Helsinki area around 5000 BC. Their presence has been documented by archaeologists in Vantaa, Pitäjänmäki and Kaarela. Permanent settlements did not appear until the beginning of the 1st millennium AD, during the Iron Age, when the area was inhabited by the Tavastians. They used the area for fishing and hunting, but due to the lack of archaeological finds it is difficult to say how extensive their settlements were. Pollen analysis has shown that there were agricultural settlements in the area in the 10th century, and surviving historical records from the 14th century describe Tavastian settlements in the area. Christianity does not gain a significant foothold in Finland before the 11th century. …

Known as the "Daughter of the Baltic" or the "Pearl of the Baltic", Helsinki is located at the tip of a peninsula and on 315 islands. The city centre is located on a southern peninsula, Helsinginniemi ("Cape of Helsinki"), which is rarely referred to by its actual name, Vironniemi ("Cape of Estonia"). Population density is comparatively high in parts of central Helsinki. The central major district had a population density of 6,588 inhabitants per square kilometre of land area in 2024, while Helsinki as a whole had a population density of 3,152 inhabitants per square kilometre in 2025. Outside the city centre, much of Helsinki consists of post-war suburbs separated by patches of forest. A narrow, 10 kilometres (6.2 mi) long Helsinki Central Park, which stretches from the city centre to Helsinki's northern border, is an important recreational area for residents. …
