Oscarsborg Fortress — Attraction in Frogn

Visited 28th Aug and was not the best experience. First, you need to get a bus from Oslo (45min) to Drobak as the boat direct from Oslo does not run midweek even though the sign at the bock says otherwise. The small boat from Drobak was pleasant but didn't have any guides like the tourist sign said (ask for a map on the boat!!) The fortress had NO refreshments to buy, so take food/drink (we did not). There were 2 restaurants (like I had read), but both shut. The best part was a five minute basic movie explaining how the Blucher was sunk, but then, for us, it didn't go into enough detail.

There is a guided tour you can do but again only peak and when at the fortress there is a sign saying you can book in advance for one (very helpful) so we didn't get to see the torpedo as this is with a guide only (from what we...

Great place for a day trip from Oslo. Oscarsborg can be reached by Ruter boats B21/B22 from Aker Brygge or by a fancy boat that can be booked through the visitoslo.com website. The Ruter tickets can be bought in the Ruter app, and the departure schedule can also be viewed there.

The fort itself is not too big but there are some exhibitions to read through the history and it's a nice place to walk around and enjoy the views. Beautiful views, at least on a sunny day!

Entry to the fortress is free. There are some cannons to look at and the island where the ferry stops links to a second island by a short bridge where there are some more hiking paths and a restaurant.

You can also take the free military shuttle over to Drøbak, a residential area with some quaint shops and restaurants. The ferry departure point is marked on the site maps and it departs...

Amazing day-trip for families and history-buffs alike. Once a military stronghold, the entire island is now accessible to the public, with museums, restaurants, and ample opportunities for a dip in the Oslo Fjord

The main fort was built built between 1844-55, and was the most modern fortress in Northern Europe. In the years after, it was expanded and strengthened with additional bastions on both sides of the fjord.

During the nazi invasion April 9th 1940, the garrison at Oscarsborg were the only obstacle for the German occupation of Oslo, and rose to the challenge.
