Stockholm is the capital city of Sweden.

It is built on lots of islands. Bridges join the islands together. On one side is a big lake. On the other side is the sea.

Stockholm is the capital and biggest city of Sweden, in northern Europe. It is built on many islands and on the mainland, right where Lake Mälaren meets Saltsjön, an arm of the Baltic Sea. Old bridges link the islands, and water is everywhere, which is why Stockholm is one of several cities nicknamed "Venice of the North."

About 985,000 people lived in the city in 2022. Stockholm has buildings from the Middle Ages right up to today, and it is home to Sweden's king, its parliament and its government.

Stockholm lies at the junction of Lake Mälaren (Mälaren) and Saltsjön, an arm of the Baltic opposite the Gulf of Finland, on numerous islands as well as the mainland of Uppland to the north and Södermanland to the south. Britannica calls it the largest city and metropolitan region in the Nordic countries and, for its waterways and its well-preserved architecture from medieval to modern, one of Europe's most aesthetically attractive capitals.

The municipality had 984,748 people in 2022 (Statistics Sweden). Stockholm is Sweden's leading industrial area and chief commercial center, home to the largest stock exchange in the Nordic countries (founded 1863) and, Britannica notes, one of Europe's leading technology centers, with one of the continent's highest start-up rates. As of 2012 the region held 22 percent of Sweden's people and produced 29 percent of its GDP.

Famous places

Stockholm's oldest part is called the Old Town.

It has narrow streets and the king's palace. In a museum, you can see a giant wooden ship. It sank long ago and was lifted out of the water. At Skansen, you can visit old houses and farm animals.

Gamla Stan, the Old Town, is where Stockholm began. Its narrow streets follow the medieval pattern, and most of its buildings are from the 1500s and 1600s. Here stand the Royal Palace, Stockholm Cathedral and the House of Parliament.

East of the Old Town is the island of Djurgården, full of museums. The Vasa Museum holds a warship that sank on its first voyage in 1628 and was raised in 1961. Skansen, founded in 1891, gathers old houses, farms and animals from all over Sweden. Across the water, City Hall hosts the Nobel Prize banquet every December.

The original nucleus, the 'city between the bridges', is Gamla Stan: Stads, Helgeands and Riddar islands. Its medieval street network and buildings, mainly of the 16th and 17th centuries, are legally protected. Stads Island holds the Royal Palace, Storkyrkan (the Church of St. Nicholas), the German Church, the House of Lords and the Stock Exchange; the Riksdag stands on Helgeands Island, and Riddarholm Church dominates Riddar Island.

On Djurgården, the Vasa Museum shows the warship Vasa: 69 m long and over 1,200 tonnes, with 64 cannons, it heeled over in a gust and sank 1,300 m into its maiden voyage on August 10, 1628, and was raised on April 24, 1961, after 333 years. Skansen, founded in 1891 by Artur Hazelius, calls itself the world's oldest open-air museum, with houses moved from across Sweden. Kungsholmen has City Hall, where the Nobel Prize banquet for 1,300 guests has been held in the Blue Hall since 1934.

From island town to capital

Nobody knows exactly when Stockholm began.

It was first written about long ago, in 1252. Traders came by boat to buy and sell. The town grew bigger and bigger. Kings and queens made it their home.

Nobody knows exactly when Stockholm was founded. It was first mentioned as a town in 1252, in letters by a Swedish ruler called Birger Jarl. It grew quickly thanks to trade with merchants of the Hanseatic League, and soon kings lived there.

In the 1600s Sweden became a great power, and in 1634 Stockholm officially became the capital. Its population grew from about 10,000 to more than 50,000. In the 1800s industry grew and many schools, museums and parks were built, and by 1900 the city had 300,000 people. Stockholm hosted the Olympic Games in 1912, and the Metro opened in 1950.

The founding date is unknown. Stockholm first appears as a town in 1252, in letters of Birger Jarl, under whom it grew rapidly and became a royal residence and administrative center; a trade agreement giving Hanseatic merchants freedom from customs and the right to settle spurred growth. In 1397 Sweden joined the Kalmar Union with Norway and Denmark; conflict followed, and in 1520 the Danish king Christian II had dozens of Swedish nobles executed (the 'Stockholm Bloodbath'). Gustav I Vasa freed the city from Danish rule in 1523.

Stockholm formally became capital in 1634, during Sweden's 'Age of Greatness', and grew from about 10,000 people to more than 50,000 by the 1670s. Defeat in the Great Northern War (1700–21) brought decline; after fires, stone replaced wood. Gustav III's reign made it a cultural center. Industrialization, municipal cleaning (1859) and sanitation (1861) drove growth to 300,000 by 1900. The city hosted the 1912 Olympics, opened its Metro in 1950 and redeveloped older districts between the 1950s and 1970s.

Through the years

Getting around Stockholm

To get around Stockholm, people cross lots of bridges.

They also ride trains under the ground. Most stations have art! Some look like caves, some have paintings, and some have statues.

Because Stockholm is spread over islands, bridges and overpasses tie the city together, linking the Old Town to the districts on the mainland to the north and south.

The Metro, or tunnelbana, opened in 1950. Since 1957 artists have helped design new stations, and older stations have been decorated too, so today more than 90 stations show art on platforms, walls or halls. Visit Stockholm, the city's official visitor guide, says the subway is said to be the world's longest art exhibition, about 110 kilometers long. Stockholm is also Sweden's second-biggest port.

Gamla Stan's islands are connected by old bridges and modern overpasses to districts on the mainland of Uppland (Norrmalm, Vasastaden, Östermalm, Kungsholmen) and Södermanland. The Metro opened in 1950, as older sections of the city were redeveloped between the 1950s and the 1970s.

Visit Stockholm, the city's official visitor site, describes the Metro as 'said to be the world's longest art exhibit', 110 km long: since 1957 artists have played a key role in each new station, and older stations built without art have since gained statues, murals and installations, so that more than 90 stations now show works of art. By sea, Stockholm is Sweden's second-largest port, after Gothenburg.

Weather and seasons

Winters in Stockholm are cold and dark.

In January, it is often around freezing. Summers are mild and pleasant. Spring is the driest time of year.

Stockholm has cold winters and mild summers. In January, the average daily high is only about 1 °C and the low about −3 °C. In July, highs average about 24 °C and lows about 15 °C.

It is not a very wet city: about 550 millimeters of rain and snow fall in a year, a little more in summer and autumn than in spring. Spring is the driest season, with only about 27 to 34 millimeters a month from March to May.

World Meteorological Organization normals for Stockholm (1991–2020) give a January mean daily maximum of 1.0 °C and minimum of −2.9 °C, and a July mean daily maximum of 23.6 °C and minimum of 14.8 °C, the warmest month. Monthly precipitation ranges from about 27 mm in March to about 66 mm in August, roughly 550 mm in total; November and December have the most days with precipitation.

Britannica credits the city's abundant waterways, Lake Mälaren to the west and Saltsjön to the east, together with its well-preserved architecture, for making Stockholm one of Europe's most aesthetically attractive capitals.

Living in Stockholm

Many people in Stockholm work with computers and new ideas.

There are big universities and museums. Every December, Nobel Prize winners come to a grand dinner here. At Skansen, you can see old houses, animals and crafts.

Stockholm is Sweden's center for culture and learning, with Stockholm University, the Royal Institute of Technology and the Karolinska Institute, a famous center for medical research. Each December, Nobel Prize winners are honored in the city, and a banquet for 1,300 guests is held in the Blue Hall of City Hall.

Many people work in technology: Stockholm has one of the highest rates of new start-up companies in Europe. About 27 percent of people in Stockholm are immigrants or have a background from another country.

Britannica calls Stockholm Sweden's cultural and educational capital: Stockholm University (1877), the Royal Institute of Technology (1827) and the Karolinska Institute, a major center of medical research; the Royal Swedish Academy of Sciences selects Nobel laureates each year. The Royal Opera, the Stockholm Philharmonic and the Royal Dramatic Theatre (Dramaten) lead its cultural life. After the award ceremony on December 10, the Nobel banquet, with 1,300 guests, is held in City Hall's Blue Hall, as it has been since 1934.

The economy combines government, finance, the Nordic region's largest stock exchange and a technology sector with one of Europe's highest start-up rates; tourism also matters. Immigration from abroad and migration within Sweden fuelled 20th-century growth; about 27 percent of Stockholmers are immigrants or of non-Swedish background, and 15 percent were born abroad. At Skansen, Hazelius soon had people demonstrating spinning, weaving and other crafts in the historic houses, a 'living museum'; today it offers music, dance, crafts, gardens and historic houses all year.

Stockholm on the map

Find Stockholm on the globe.

It is in Sweden, in the north of Europe. It sits on the east coast, by the Baltic Sea. Look for the lake and the many islands!

Stockholm is on the east coast of Sweden, in northern Europe. To its west is Lake Mälaren, and to its east is Saltsjön, a bay of the Baltic Sea that faces the Gulf of Finland.

The city's center is the Old Town, on islands between the lake and the sea. North of it lies the busy shopping district of Norrmalm, and to the east is the island of Djurgården, with its museums.

Stockholm lies at about 59.4° N and 18.1° E, where Lake Mälaren drains into Saltsjön, an arm of the Baltic opposite the Gulf of Finland. The city occupies islands and the mainland of two historic provinces, Uppland to the north and Södermanland to the south.

Gamla Stan sits at the hinge between lake and sea. Norrmalm, north of it, is the modern shopping, business and financial center; Kungsholmen, to the west, has City Hall; and Djurgården, to the east, is a cultural and recreational island of museums and parks.

Amazing facts

  • People once had ideas like filling the sunken Vasa with ping-pong balls to raise it!

    Ideas for raising the Vasa included filling it with ping-pong balls or freezing it in a giant ice cube. Divers used cables instead.

  • Skansen's old houses once had dolls inside instead of people.

    When Skansen began, its old houses were filled with dolls in traditional clothes. Soon real people took their place, showing spinning and weaving.

    Hazelius first furnished Skansen's relocated houses with costumed dolls, but soon replaced them with people demonstrating spinning, weaving and other crafts, creating a 'living museum'.

  • The Vasa lay under the water for 333 years.

    The Vasa lay on the bottom of Stockholm's harbor for 333 years before it was lifted out in 1961.

    Vasa rose on April 24, 1961, 333 years after sinking; Swedish Television broadcast the lift live across Europe.
