Geography Norway, Sweden and northern Finland form the Scandinavian peninsula more than 2'000 kilometers from south to north. Denmark is a peninsula stretching out from continental Europe, accompanied with an archipelago of large and small islands, while Iceland is situated in the middle of the Atlantic Ocean. Except for Iceland, the countries are situated relatively close to each other, often sharing borders with one another. They do not really form a geographical unit, but this is rather irrelevant since seas and waterways have historically, instead of separating peoples, united them. And we are, after all, talking about the best seafarers of ancient Europe.
Some tourists even travel by bicycle.
Language Swedish, Danish, Norwegian, Icelandic and Faroese are all North-Germanic languages developed from the Old Norse spoken in Viking age Scandinavia. A Swede, a Dane and a Norwegian can understand each other with varying degrees of difficulties, but none of them will fully understand Icelandic or Faroese without studying the languages. Finnish is an entirely different case, it's a Finno-Ugric language related to Estonian and Hungarian. There is, however, a Swedish-speaking minority in Finland, which ties it linguistically to Scandinavia. The way this melodic accent is expressed vary quite a lot between different dialects, but the dichotomy exists everywhere having an important role to differentiate between words which otherways would have been confused.
