I spent the last five nights of my 2006 Scandinavia trip in Oslo, where I filled four days with sightseeing, exploring and museums. Oslo is the capital of Norway, and sites I visited date as far back as a thousand years - and more if I count the Viking ships and archeolgical finds. Some interesting museums, parks, and the Akershus Festning all made for a very interesting visit.
