Akershus festning - During my visit to Oslo, I simply could not miss Akershus Fortress, and this…read moreplace made a great impression on me. The historic fortress is exceptionally well preserved and offers stunning views of both the Oslofjord and the harbor. I really enjoyed the combination of rich Norwegian history and the peaceful atmosphere that can be found here. Walking along the ramparts, courtyards, and ancient buildings was a wonderful experience. The entire area is well maintained, clean, and perfect for exploring at a relaxed pace. It is a place where you can comfortably spend several hours while learning more about the history of Norway. Admission to the fortress grounds was free, with charges applying only for the museums. I also appreciated that the visitor center provided free drinking water and free soda from a dispenser. We were able to refill our bottles as well. The toilets located around the site were also free to use.
