The three largest cities in Sweden are Stockholm, Gothenburg and Malmö.
The main part of Stockholm is situated in the region of Uppland, and a smaller part belongs to the region of Södermanland. Stockholm is also the capital of Sweden.
Gothenburg is the largest city in the region of Västergötland and the second largest city in Sweden. Malmö is situated further south, in the region of Skåne, and is the third largest city.
Stockholm is well known for The Swedish Royal Castle and of course for beeing the home town for at least parts of the royal family. It’s also known for Skansen, Djurgården, Drottningholm castle, The Abba Museum, Vasamuseet and many other turist sights.
Gothenburg is sometimes referred to as being the friendliest city in Sweden. It is known for the large amusement park Liseberg, but also for its fishmarket, cosy cobble stoned streets, car free shopping areas and its blue trams.
In Malmö you’re right next to the waterfront and Öresundsbron, which will take you to Denmark in almost no time. Therefor many tourists ususally combine a visit to Malmö with a visit to Copenhagen.
Other than that Malmö is a really cosy town, rich in gastronomical and cultural variety and known for its many green areas and long sand beaches.
