Introduction

Akershus Fortress has guarded the entrance to Oslo's harbour since King Håkon V began building it in 1299. The medieval castle and its Renaissance fortress grounds are free to wander: ceremonial halls, a castle church and the Royal Mausoleum sit within thick walls, a Resistance Museum recalls Norway's WWII occupation, and ramparts offer sweeping Oslofjord views. Across the bay on the Bygdøy peninsula, the famous Viking Ship Museum is being transformed into the new Museum of the Viking Age — check its current status before visiting.

✨ Highlights

Medieval Castle Halls

Seven centuries of royal and military history, explored on guided tours through the castle interior.

Fjord & Harbour Views

Ramparts overlook the Oslofjord, ferry routes and the opera house across the water.

Resistance Museum

A compact WWII museum within the grounds covering Norway's five occupation years.

Royal Mausoleum

The castle church crypt is the resting place of modern Norwegian royalty, still in use.
