The Kingdom of Sweden is a parliamentary monarchy in Northern Europe with around 10 million inhabitants. Sweden is a member of the European Union and the Nordic Council. The country borders the states of Norway and Finland as well as the Baltic Sea. The official language is Swedish, while 80% of the population speaks English as a foreign language. The local currency is the Swedish krona, the exchange rate for one euro is almost SEK 10.

The country's twelve largest cities are Stockholm, Gothenburg, Malmö, Uppsala, Linköping, Västeras, Örebro, Helsingborg, Norrköping, Jönköping, Umea and Lund.

Sweden's largest industry is vehicle construction with brands such as Volvo, Scania and Saab. The furniture manufacturer Ikea and the fashion brand H&M are world-famous.

The capital of Sweden is Stockholm with around 950,000 inhabitants. Stockholm is the largest city in Scandinavia with a metropolitan area of over two million people. The city is also the seat of the Swedish parliament and the Swedish government. It is also the country's cultural center and episcopal seat.

Stockholm's sights include the old town on the city island, the Royal Palace, the Royal Swedish National Opera, the Stockholm House of Culture, the Vasa Museum, the Nordic Museum, the Reichstag building, the Hay Market, the Stockholm Town Hall, the Knight's House, the Bonde Palace, the Katarina Church, the Ticino Palace, the ABBA Museum, the nature park on the Djurgarden peninsula, the Globen with its SkyView, Södermalm and the Gröna Lund amusement park.

In recent years, tourism has grown into an important economic indicator, and the number of overnight stays in the capital has now risen to over seven million. Festivals such as the Stockholm Water Festival, the Stockholm Marathon or the Midsommerfest are important attractions and attract numerous foreign tourists.

Significant attractions outside the capital include the Ice Hotel in Jukkasjärvi, the Öresund Bridge in Malmö, the Liseberg amusement park in Gothenburg, Lund Cathedral, Drottningholm Castle in Ekerö, the Turning Torso in Malmö, Gripsholm Castle in Mariefeld, the southern coastal town Ystad, the Haga district in Gothenburg, Visby Cathedral, the Viking settlements, Uppsala Cathedral, Sofiero Castle in Helsingborg and the Botanical Garden in Gothenburg.

So far I've traveled to Stockholm twice, but unfortunately I haven't been to the interior of Sweden yet. The city itself is very pleasant and you can walk around at your leisure to look at the few interesting buildings. The red bus covers almost every corner and you get a complete impression of the city. Otherwise, Stockholm didn't particularly impress me, but maybe I'll get the opportunity to get to know the entire country at some point.
