Peter the Great has nothing to do with it
Older accounts open with two paragraphs on Peter the Great's influence on Helsinki and then concede that he died a century before the cathedral was begun. The concession should have ended the paragraph. Peter the Great died in 1725; building started in 1830.
The people who matter are three. Alexander I made Helsinki the capital in 1812 and ordered the centre rebuilt. Johan Albrekt Ehrenström drew the town plan. Carl Ludvig Engel, a German architect who spent his career here, designed the buildings — the cathedral, the Government Palace, the university's main building and library — and gave the city the single neoclassical centre it still has.
The building
It went up on the site of the demolished Ulrika Eleonora church. Work began in 1830 and it was inaugurated on 15 February 1852, twelve years after Engel's death in 1840.
The work was finished by Ernst Bernhard Lohrmann, who did not merely execute Engel's drawings but altered the silhouette. The four small corner domes are his, and so are the bell tower, the chapel beside the front steps, and the zinc statues of the Twelve Apostles that stand along the roofline, put up in 1849. Those figures are the apostles rather than the angels older accounts take them for, and they are the reason the roof has a crowded, populated look from below.
It was St Nicholas' Church, and the name changed twice
This is a detail older accounts miss entirely. The cathedral was St Nicholas' Church — Nikolainkirkko — and the name worked two ways at once: for Tsar Nicholas I, who initiated the project, and for St Nicholas, the patron saint of seafarers, in a city that lived by the sea.
The change was not a single event at independence. After 1917 the name Suurkirkko, the Great Church, became the usual one, and the building became Helsinki Cathedral only in 1959, when the Diocese of Helsinki was founded and it acquired a bishop. It is a working cathedral, and the bishop's seat.
Admission is now charged
Entry was free when older accounts were written. It is not now, and this is part of a general change across central Helsinki — Temppeliaukio started charging in 2017 and most of the central churches have followed.
- A charge applies through the summer and autumn season, which has been extended once already and may be again, so the months it covers should be checked rather than assumed.
- Outside that season the payment is voluntary, at a self-service point.
- Nobody attending a service pays, and nor do under-eighteens, parish members, school groups with a teacher, or visitors with mobility impairments and those assisting them. Students, pensioners and larger groups pay a reduced rate.
- In high summer there are free evenings, run by volunteers, on weekday evenings — a good way in for anyone who objects to paying to enter a church.
- Helsinki residents can get a free church pass covering the central churches for part of the year, parish membership not required. It is of no use to a visitor but explains why the person ahead in the queue is not paying.
- A combined ticket covers the cathedral with the Old Church and St John's.
Opening hours shift with the season and with church events, and the building closes to visitors for services and weddings.
Steps, and getting in without them
The cathedral stands at the top of a broad flight of granite steps, which is the whole point of the composition and a real obstacle. Various step counts circulate; none of them comes from the cathedral, so none is given here.
There is a step-free entrance, by way of the crypt — but the crypt is closed from November to the end of May, which means the accessible route is seasonal. Anyone who needs it in winter should contact the cathedral first rather than arrive and find out.
The crypt itself is worth the detour in summer, when it is free, and holds a café and changing exhibitions.
How Lutheran is Helsinki now?
Older accounts put Lutheran church membership at over eighty per cent of the city. That was roughly true in the 1990s and is well out of date. Nationally the figure is now around six in ten, and in Helsinki it is lower than that — the city is both less religious and more religiously varied than the rest of the country, with a fifth of residents now having a first language that is neither Finnish nor Swedish.
Senate Square
The square below is Engel's, and it is worth standing in the middle of it. The Government Palace is on the east side, the University of Helsinki's main building opposite it on the west, with the University Library behind. The south side keeps a row of eighteenth-century merchant houses that predate the whole scheme, including the Sederholm House, the oldest building in central Helsinki.
In the middle stands the statue of Alexander II, unveiled in 1894 — the tsar remembered here as the one who left Finland's autonomy alone, which is why it survived both an attempt to destroy it in 1917 and the calls to remove it after independence.
