Oslo is a major tourist destination but, fortunately for me, not in February. The competition in the museums wasn't from coach loads (or, worse, cruise-ship loads) of camera-toting tourists, but from legions of back-pack-wearing primary school kids.
I decided to stick to my maritime tourist theme for this trip and after wandering along the snow-covered quay sides, found a bus to the museums ghetto on Bygdoy peninsula a few miles west of the city centre. In the summer there is a ferry across the fjord to Bygdoy, but at this time of year the 'only way is bus' - as the young women in the tourist office assured me. Since the bus is the only way, it's the route that the school groups take too. The seven year old (I'm guessing) sitting beside me was happy to chatter in English about his school trip to see the Viking boats - his English being very much better than my Norwegian.
Fram Museum - before going to see the Fram, the ship that Amundsen used on his successful trip to the South Pole in 1911. The boat itself is very similar to the Discovery I've visited a few times in Dundee, but despite being out of the water the Fram is in a much more original condition than the Discovery.
Norwegian Maritime Museum, which covers about 2000 years of water-borne history from dug-out canoes though to specialist oil rig vessels and bulk carriers and has examples of some of the older, smaller boats plus fantastic models of the bigger and newer vessels. There is a really good video presentation that flies you along the Norwegian coast from the Lofoten Islands round to Oslo, and combines both modern (helicopter-shot) video footage with historical photographs from the early 20th Century.
Viking ship museum - which houses three original Viking longships from various parts of Norway. All three were used as funeral vessels, and were buried with everything needed for the next life. Two of the ships look as if they could, once the ice had cleared, be moved off to the closest fjord and sailed away.
Akershus Fort in the centre of the city, with beautiful views over the harbour, the city and along Oslofjord too, which almost, but not quite provided a sunset.
Norwegian Royal Yacht. I'm told that this is one of only two Royal Yachts still in service in Europe, the other one is Danish.
