The Holy Trinity Church (fi|Pyhän Kolminaisuuden kirkko, sv|Heliga Treenighetskyrkan, ru|Свято-Троицкая церковь) is a Finnish Orthodox Church located in the Kruununhaka district of Helsinki, on the corner of Unioninkatu and Rauhankatu. The church was built in the neo-classical style in 1826 under the direction of the architect Carl Ludvig Engel, and was dedicated and opened in the following year.[1] [2] The Holy Trinity services the city's orthodox community with Divine Liturgy held in both Church Slavic and Finnish.[3]
The church is Helsinki's oldest Orthodox church.[4] When Finland became 1808 autonomic Grand Duchy of Finland, a number of Russian civil servants, merchants and soldiers moved to Helsinki. They needed a place for worship, and the czar supported their efforts to get a church. In the 21st century, many of the churchgoers still speak Russian, but majority of them are immigrants born in the Soviet Union.[5]
