HelsinkiHelsinki (Helsingfors)

Helsinki was founded in 1550 by King Gustav Vasa of Sweden, who wanted a trading town on the Gulf of Finland to compete with Tallinn across the water. The first site, at the mouth of the Vantaa river, was poor: the harbour was shallow, the town was small and plague and fires kept it weak. In the 1640s it was moved to the peninsula where the city centre stands today.

The real turning point was military. In 1748 Sweden began to build the Sveaborg fortress on islands off the coast to guard against Russia, and Helsinki became a garrison town. The fortress did not hold: in 1808 to 1809 Russia took Finland after a war, and Sveaborg surrendered. Finland became a Grand Duchy inside the Russian Empire, with its own laws and Lutheran church.

In 1812 Tsar Alexander I moved the capital from Turku, in the south-west, to Helsinki. The reason was politics: Turku was too close to Sweden and Helsinki was closer to St Petersburg. A great fire in Turku in 1827 helped, because it destroyed the university's home; the university moved to Helsinki in 1828. The tsar commissioned the German-born architect Carl Ludvig Engel to design a new centre.

Finland declared independence on 6 December 1917, in the turmoil after the Russian Revolution. A civil war followed in 1918 between the Reds and the Whites, and Helsinki was held by the Reds for a period before the Whites took it back. The city was bombed in the Winter War of 1939 to 1940 and again in 1944, but escaped the heavy destruction that hit other European capitals. It hosted the 1952 Olympic Games, the first in the Nordic country, and rebuilt itself in the postwar decades into a design-minded, high-tech capital.

Today Helsinki has about 690,000 residents and around 1.5 million in the metropolitan area. Finnish and Swedish are both official languages, which is why every street sign carries two names. The city ranks among the safest and most liveable capitals, and it is still small enough to cross on foot in half an hour.

Carl Ludvig Engel designed the centre from the 1820s. Senate Square is the core: the Senate building on the east side, the university on the west, the Cathedral on the north, and a broad flight of steps rising to it. Engel wanted a city that looked like St Petersburg in miniature. The yellow, white and grey facades, the wide squares and the straight streets come from that plan and it is still the reason the centre feels so orderly.

The Helsinki Cathedral, finished in 1852 after Engel's death, is a white Lutheran building with a green dome and twelve apostle statues on the roof. The contrast beside it is the Uspenski Cathedral, a red-brick Orthodox church on Katajanokka finished in 1868, with gold onion domes. Together they mark the two churches of Finnish history: Lutheran Sweden and Orthodox Russia.

The next wave was National Romanticism and Art Nouveau (Jugend) around 1900. Architects such as Eliel Saarinen, Herman Gesellius and Armas Lindgren built blocks with granite, dragon-like ornament and Finnish myth in stone. The Central Station, designed by Saarinen and completed in 1919, is the best-known example, with its giant lamp-bearing statues at the entrance and a clock tower. Katajanokka and the Eira district hold rows of Jugend apartments.

Functionalism came in the 1930s, and Alvar Aalto is the name to know: his Finlandia Hall, Academic Bookstore and National Pensions Institute show his mix of white marble, brick and daylight. From the 1960s came the Temppeliaukio Church, blasted into a granite outcrop by the Suomalainen brothers, and, more recently, Kiasma museum (1998), Oodi library (2018) and the wooden Löyly sauna (2016).

The result is a compact tour of a century of architecture in a city you can walk in an afternoon. If you are short of time, take a tram past the Jugend blocks in Eira, walk Senate Square to Uspenski, and finish with a look at Oodi's wooden curve.

There are roughly three million saunas in Finland for about five and a half million people. The sauna is where Finns wash, recover, negotiate and celebrate. Historically it was also where they gave birth and where the dead were prepared, a place treated with quiet respect. That is why the rules of behaviour are gentle but firm: keep your voice low, be naked or follow the venue's swimsuit rule, and never treat it as a party.

The classic Finnish sauna is heated to about 70 to 100 degrees with a wood or electric stove. You sit on a bench, throw water on the hot stones to make a burst of steam (löyly), stay until you are hot, then cool off in the sea, in a lake, under a cold shower or in snow. Then you rest, drink water or a beer, and repeat. Three rounds over an hour or two is normal.

In Helsinki you can try three types. The modern public sauna, such as Löyly or Allas Sea Pool, is built for visitors and needs a booking. The old workers' sauna, such as Kotiharju in Kallio (wood-heated, dating from 1928), is a local place with separate sessions and a plain look. The smoke sauna (savusauna) has no chimney: the room is smoked, aired and then used, and the air is soft and slightly sweet.

Winter swimming in a hole in the sea ice (avanto) is common. Many Finns swear it makes them healthier; scientists say the evidence is modest, but it is a ritual that people love. If you try it, get warm first, keep your dip to a minute or two, do not drink alcohol beforehand and have a warm room ready.

For a visitor the sauna is also the best way to meet the country at its calmest. Take a swimsuit and a small towel in your bag, check the venue's rule for swimwear and for gender, and book the evening slot before you land.

One practical point: rules differ by venue and by session. Some sessions are mixed with swimwear, some are separate for women and men, and a few older saunas expect you to go without. Check the rule on the booking page, bring a swimsuit as a backup, and never take photographs inside a sauna.

Finnish food rests on what the land and sea provide: fish, rye, potatoes, berries, dairy and game. Salmon soup (lohikeitto) is the everyday lunch, made with cream, potato and dill. Baltic herring (silakka) is grilled or pickled and sold fresh at the Market Square in the autumn fair. Reindeer, sautéed with lingonberries and mashed potato, is the dish most visitors try once.

Bread is dark rye, and the Karelian pie (karjalanpiirakka) is a rye crust with rice porridge, eaten with egg butter. The cinnamon-and-cardamom bun (korvapuusti) is a national institution, along with the doughnut (munkki) at Vappu. Leipäjuusto, or "bread cheese", is a mild baked cheese served warm with cloudberry jam.

Coffee is central: Finland is at or near the top of the world for coffee drunk per head. Coffee breaks at work are taken seriously, and a kahvi with a pulla (sweet bun) is the standard afternoon stop. Chocolate is Fazer, the local firm that started in 1891, and the salty liquorice (salmiakki) is an acquired taste.

The eating day is early: lunch about 11:00 to 14:00, dinner about 17:00 to 20:30, and most kitchens close by 21:00 or 22:00. The lunch buffet (lounas) is the best-value meal of the day, often with a salad, soup, main and bread for €12 to €18. Markets and market halls, including the Old Market Hall and Hakaniemi, are the best places to sample.

Restaurants have moved towards a New Nordic approach, using local, seasonal produce and simple methods. It is expensive, but a set lunch at a good restaurant is a route in. For a cheaper approach, a picnic of fish, cheese, rye bread and berries from Hakaniemi, eaten on a park bench, is one of the best-value meals in the city.

Two habits help a visitor: eat your main meal at lunch, when the buffet price is lowest, and treat the afternoon coffee and bun as a proper meal. Check opening hours on Sundays and public holidays, when the market halls and many restaurants close or shorten their hours.

The year is a swing between two extremes. In late December the sun rises after 09:00 and sets before 15:15, so you get about six hours of daylight. In late June the sun sets after 22:45 and never gets fully dark: the Finnish summer night is a long twilight. The change is fast, gaining about six minutes of light a day in spring.

This is why the seasons shape the city more than in most capitals. Winter is a time for saunas, cafés with candles, Christmas markets and museums, and Finns light candles and lamps in every window. Snow is common from December to March, and when the sea freezes near the shore, people walk and ski on it. Bring boots with grip, a windproof shell and a hat.

Spring arrives quickly. By April the light is bright, the snow melts, and the first terraces open. On 1 May (Vappu) the students celebrate in the parks and the city throws a picnic; it is one of the biggest days of the year. May and early June are among the best times to visit, with long days and few crowds.

Summer is short but generous. Locals leave the city at Midsummer, going to summer cottages by lakes, and for a few days Helsinki is nearly empty. July is warm, sometimes 25 degrees or more, and terraces, sea swimming and island ferries all run. Some restaurants close for the summer holidays.

Autumn brings the colours (ruska) in September and the Baltic Herring Fair in October. Then the light drops quickly, and November is dark and damp, often the least attractive month for visitors. The best times to come are May to September, or December if you want a Christmas market and a sauna.

A last practical note on packing: layers matter more than a single heavy coat, because trams, shops and museums are well heated and the wind on the harbour is cold. Add a small towel and swimsuit for saunas, boots with grip in winter, and a light rain jacket for autumn and summer showers.
