About Akershus Fortress
Akershus Fortress is a medieval castle and stronghold strategically located on the Oslofjord that has protected the city since the late 13th century. Over the centuries, it evolved from a royal medieval residence into a formidable Renaissance fortress and military complex. Today, it remains an active military base as well as one of Oslo's most beloved public parks and historic landmarks.

Plan your visit
Visit on a clear afternoon in spring or summer to enjoy pleasant walking temperatures and stunning sunset views over the fjord. If you prefer quiet grounds with fewer crowds, arrive early in the morning when the fortress gates first open.
Entering the fortress grounds and ramparts is completely free to the public year-round. An admission fee applies if you wish to enter the castle interior or on-site museums, and tickets can be bought upon arrival.
The fortress is just a 10-minute walk south from Oslo Central Station or Oslo City Hall. You can also take tram line 12 to the Christiania torv stop or the Kontraskjæret stop near the fortress gates.
Tips for visiting
- Wear comfortable, sturdy walking shoes because the grounds feature steep cobblestone hills and uneven stone steps.
- Bring a camera to capture scenic vistas of the Oslofjord, the harbor, and City Hall from the bastion walls.
- Check the schedule in advance if you want to witness the daily ceremonial changing of the guard.
- Pick up an informational map at the visitor center near the main gate to help navigate the large complex.
- Dress warmly with windproof layers if visiting outside of summer, as harbor winds atop the ramparts can feel chilly.
