About Helsinki Cathedral
Helsinki Cathedral is the Diocese of Helsinki's Evangelical Lutheran cathedral. It stands on Senate Square in Kruununhaka, in central Helsinki. It was built between 1830 and 1852 as a tribute to Nicholas I of Russia, who was Grand Duke of Finland. Until Finland declared full independence in 1917, it was also called St Nicholas's Church. It went up on the site of the smaller Ulrika Eleonora Church, which dated from 1724 to 1727.
Carl Ludvig Engel designed the cathedral as the climax of his layout for Senate Square, and it is surrounded by smaller buildings of his. Its style is neoclassical, and a tall green dome is surrounded by four smaller domes. It follows a Greek-cross plan: a square center with four arms of equal length, mirrored in all four compass directions. Every arm's facade has a colonnade and a pediment. Engel died in 1840, and his successor Ernst Lohrmann altered the building later, adding the four small domes.
Construction began in 1830, and the cathedral was officially inaugurated on February 15, 1852. In 1849, larger-than-life zinc statues of the Twelve Apostles were put up along the roofline, at its apexes and corners. After Finland became independent, names meaning Great Church replaced the old one, the Finnish Suurkirkko and the Swedish Storkyrkan, and in 1959 it received its present name. Its nickname is the White Cathedral, although its walls are painted in nearly identical light gray shades.
