Oscarsborg Fortress reviews
this is a massive Fortress and so much to look at and place is just amazing we had a great time looking around again Johanna told us of the history about the Fortress "GREAT PLACE TO VISIT" more »
Yes it is worth a visit, despite not being truly authentic anymore. The views form the windows and the grounds back across Oslo Fjord are worth the visit alone. more »
Beautiful touristic place, but be sure not to miss your ferry on its way back if you don't want to pay a ticket for an expensive 10-minute ferry to Drøbak and going back to Oslo from there.
Historic and very nice. Good food in the restaurants.
