Built in 1299, Akershus Castle was built around the port due to strategic considerations at the time. The castle is surrounded by grassy parks and faces the azure coast, showing the stunning Nordic nature. Denmark-Norwegian King Christie IV once lived here, so there are several research-worthy rooms in the castle. The interior is gorgeous and retro, which reminds people of the unique historical charm of the Middle Ages.
