**Unioninkatu** ([Swedish](/source/Swedish_language): *Unionsgatan*, both meaning "Union Street") is one of the key streets in the historic centre of [Helsinki](/source/Helsinki), [Finland](/source/Finland). It stretches from the [Tähtitorninvuori](/source/T%C3%A4htitorninvuori) hill to the [Pitkäsilta](/source/Pitk%C3%A4silta) bridge and is about 1.5 km long. Its southern part is located in [Kaartinkaupunki](/source/Kaartinkaupunki) up to the [Esplanadi](/source/Esplanadi) park, while the northern part acts as the border between [Kruununhaka](/source/Kruununhaka) to the east and [Kluuvi](/source/Kluuvi) to the west. The street functions as a local assembly street.[1]

In the south, Unioninkatu is directly continued by the short street Kopernikuksentie leading to the gate of the [Helsinki University Observatory](/source/Helsinki_University_Observatory). In the north, Unioninkatu is directly continued after the Pitkäsilta bridge by the street [Siltasaarenkatu](https://en.wikipedia.org/w/index.php?title=Siltasaarenkatu&action=edit&redlink=1) leading to the [Kallio Church](/source/Kallio_Church). Together these three streets form a 2.5 km long street line called [Unioninakseli](https://en.wikipedia.org/w/index.php?title=Unioninakseli&action=edit&redlink=1), the longest continuous straight street line in central Helsinki.

The northern end of Unioninkatu from the Kaisaniemi roundabout to Pitkäsilta is a busy traffic route, and forms a part of a road leading to [Hakaniemi](/source/Hakaniemi) and then to [Hämeentie](/source/H%C3%A4meentie) together with [Kaisaniemenkatu](https://en.wikipedia.org/w/index.php?title=Kaisaniemenkatu&action=edit&redlink=1) and Siltasaarenkatu. Many [tram lines](/source/Trams_in_Helsinki) and all [bus lines](/source/Buses_in_Helsinki) traveling from the [Rautatientori](/source/Rautatientori) square to the northern and northeastern parts of Helsinki and towards eastern [Vantaa](/source/Vantaa) run along it. This part of Unioninkatu is a bit wider than the rest of the street and contains a gate leading to the Kaisaniemi botanical gardens.

## History

The middle part of Unioninkatu, approximately located between the [Helsinki Market Square](/source/Helsinki_Market_Square) and the [Senate Square](/source/Senate_Square%2C_Helsinki), was already present in the 17th century after the city of Helsinki had been moved to the [Vironniemi](/source/Vironniemi) peninsula. At that time it was named Västra Kyrkogatan (Läntinen Kirkkokatu, meaning "Western Church Street") as it ran past of the Ulrika Eleonora Church that was still present at the time.[2]: 13 At that time the street leading north from the centre, to the present-day street [Hämeentie](/source/H%C3%A4meentie), was located a bit further east, partly at the location of the present-day street [Snellmaninkatu](https://en.wikipedia.org/w/index.php?title=Snellmaninkatu&action=edit&redlink=1) and had many curves.[2]: 18

When [Johan Albrecht Ehrenström](/source/Johan_Albrecht_Ehrenstr%C3%B6m) made a new [zoning](/source/Zoning) plan for Helsinki that had been chosen as the new capital of Finland in 1812, Unioninkatu became a key street running straight from Pitkäsilta to the south, to the [Ulriikanporinvuori](/source/Ullanlinna) hill, now known as Tähtitorninvuori. An astronomical observatory was later built at the southern end of the street. The street got its name when emperor [Alexander I of Russia](/source/Alexander_I_of_Russia) visited Helsinki in 1819 and arrived in the city on this street.[2]: 18 At that time the Helsinki city council proposed naming the street Aleksanterinkatu in his honour and also naming one of the streets leading east from it Elisabetinkatu in honour of his wife [Elizabeth](/source/Elizabeth_Alexeievna_(Louise_of_Baden)). However, the emperor decreed that it should be named Unioninkatu in honour of the union between Finland and Russia as agreed at the [Diet of Porvoo](/source/Diet_of_Porvoo). The emperor did accept the name Elisabetinkatu, and the street still bears the Swedish name Elisabetsgatan to this day, however its Finnish name has now been changed to [Liisankatu](https://en.wikipedia.org/w/index.php?title=Liisankatu&action=edit&redlink=1).[2]: 91 The name [Aleksanterinkatu](/source/Aleksanterinkatu) was later given to one of the streets running across Unioninkatu in 1833.[3]

In the early days of Finnish independence, there were requests to change the name Unioninkatu. Suggestions for a new name included Itsenäisyydenkatu ("Independence Street") and Yliopistonkatu ("University Street"). Regardless of this, the name was not changed.[2]: 94

The part of Unioninkatu between the Market Square and the Senate Square was the most prominent commercial street in Helsinki in the late 19th century.[4] The [Stockmann](/source/Stockmann) department store was located on the street in the so-called [Kiseleff House](https://en.wikipedia.org/w/index.php?title=Kiseleff_House&action=edit&redlink=1), which later contained only offices, but which now hosts a shopping centre.

## 2024 rename proposal

In May 2024, Dimitri Qvintus, an assistant to the [Prime Ministers](/source/Prime_Minister_of_Finland) [Antti Rinne](/source/Antti_Rinne) and [Sanna Marin](/source/Sanna_Marin) proposed renaming Unioninkatu to "Euroopan unionin katu" ("[European Union](/source/European_Union) Street"). According to Qvintus, Russia is now a criminal state engaged in an illegal war, so the union between Finland and Russia that the street was named after no long exists. Qvintus also explained that other streets in Helsinki have also changed names, such as [Mannerheimintie](/source/Mannerheimintie) which was previously named Läntinen Viertotie and Heikinkatu before that.[5]

## Buildings

Buildings on the southern part of Unioninkatu along the Tähtitorninvuori park include the German Church in Helsinki and the [Svenska normallyceum i Helsingfors](/source/Svenska_normallyceum_i_Helsingfors) school. The [Helsinki Market Square](/source/Helsinki_Market_Square) is bordered by Unioninkatu to the west, and the street separates it from the [Esplanadi](/source/Esplanadi) park. Slightly to the north Unioninkatu also runs along the western edge of the [Senate Square](/source/Senate_Square%2C_Helsinki), where the main building of the [University of Helsinki](/source/University_of_Helsinki) is located on the street. Between the Senate Square and the [Kaisaniemi](/source/Kaisaniemi) roundabout there are only public office buildings on the street, of which most were designed by [Carl Ludvig Engel](/source/Carl_Ludvig_Engel). Immediately to the north of the Senate Square are the [Finnish National Library](/source/Finnish_National_Library) and the [Helsinki Cathedral](/source/Helsinki_Cathedral) located opposite each other, with the proper main entrance to the cathedral actually located on Unioninkatu, not at the Senate Square. The Orthodox [Holy Trinity Church](/source/Holy_Trinity_Church%2C_Helsinki) is located to the north of the cathedral. After this there are hospital buildings on either side of Unioninkatu, including Topelia and the Old and New Clinics, which are now in use of the university and form part of the [City Centre Campus](/source/City_Centre_Campus). The [Metsätalo](https://en.wikipedia.org/w/index.php?title=Mets%C3%A4talo&action=edit&redlink=1) building of the university is also located on Unioninkatu.[2]: 82
