Introduction to Oslo: Oslo is located in southeastern Norway. It was founded in 1048 AD and became the capital of Norway in 1814. The entire city is close to the twists and turns of the Oslo Fjord, backed by the towering Holmenkollen Mountain. It not only has the charming scenery of a seaside city, but also has the majestic momentum of relying on the mountains and dense forests. The natural environment is very beautiful.
