    The Akershus Fortress is well worth a visit any time of year. You can pay to get into the resistance museum or the castle, or just walk around the fortress free. You can get some good pictures if you come here at dusk. There is also a restaurant with a good view should you get hungry.

    We didn't actually go inside but it's FREE entrance we just walked around the ground/ramparts as there are some beautiful views of the harbour. If you are on a visiting cruise ship you could actually dock next to the fort. Plenty of benches & it's also next to the town so very easy to find from wherever you are staying.

    I was surprised you do not have to pay entrance fee for the place. Its quite big and you can see there a lot old and interesting buildings. If you love rocks like me, you will love the place. There is a church with guided tours, they have a museum here , nice toilets and books. The view from the very top is amazing. You can see town and Bygdoy over the water and wide blue sea. Lovely place.

    A nice spot without any entry fee. Nice view over the harbor. In walking distance to Carl Johan.

    It's fun to just walk around this area and lose yourself in the views and older architecture. The cobblestone alley is different from the rest of Norway's roads. The older buildings are cool to see. We couldn't enter any. Not sure if that's ever a possibility. There seems to be a lot of history here but we didn't see signs detailing anything. There'sof open vistas in this area since it's atop a hill.

    Worth a visit - loved it! Despite the castle being (unfortunately) closed due to restoration during summer 2018, the fortress is still accessible - and for free. It is also open until late and a very pleasant place to take a stroll along walls that are centuries old and that have many stories to tell. Great views of the fjord as well!

    A lovely place, with multiple museums available. They also do guided tours around the site, which help to learn about the history and physical features. It's fairly large and spread out, so be ready to walk for a bit on the cobblestones.

    Beautiful fortress at the port of the Oslo city. Nice place to walk around and take some memorial photos. Beautiful views of the port from the spot of the fortress historical canons. Medieval buildings and atmosphere, absolutely worth visiting.

    Looks amazing from most angles alongside the Oslo pier but the beat views are probably inside the fortress. It closes pretty late compared to most Oslo attractions which is a plus and you get great views of the city below.

    Wonderful insight into the lives of Vikings. The food facilities are good and provided an enjoyable meal from a small selection of hot and cold food and beverages. The dining hall is decorated with reindeer furs at all the tables. A very enjoyable experience eating there.
