I've been lucky enough to have visited a lot of incredible places and seen a lot of amazing things but the experience of walking into the Vasa museum and seeing the ship in real life is up there with one of the most surreal and breathtaking experiences I've ever had.
For me, going to Oslo and walking around inside "Fram" was much more amazing.
Sweden has Wasa, a ship that sank after 3km on her maiden voyage.
Norway has the most successful polar explorers in the world, and Fram was the most successful ship, used in overwinterings by both Nansen and Amundsen.
