Akershus Fortress and Castle
The Akershus Castle has a very dramatic history. Founded in the 13th century, it withstood a Swedish siege in 1308 but was completely destroyed by a fire in 1527 caused by a lightning strike. After these events, the castle was rebuilt.
The Akershus Fortress is the first example of stone architecture in Norway. Today, behind its massive walls, you will find a grand Renaissance-style palace, a royal chapel, and two museums — one dedicated to the Norwegian resistance and the other to the history of the fortress's construction. Don't miss the impressive changing of the guard ceremony (at 13:30), stroll through the palace halls, visit the chapel, and of course, enjoy the stunning views of Oslo and the harbor.
