Not clear why

These are outside the Oslo Opera House. They are tanks of the Swedish army, I don't know why they're in Oslo, why they are outside the Opera House or why they have words painted on them. Eye catching, for sure, and a welcome distraction to the major road works around the Opera House which is only accessible by foot, and therefore requires absolute vigilance as a pedestrian in a foreign country. To be fair, the driving here is very restrained and there are plenty of crossings.

The Opera House's distinguishing feature is that you can walk on the roof. It's, well, ok, but not as exciting as the guidebook seems to think. I feel I may have come to the end of Oslo's attractions to be honest! Perhaps being here between the seasons (summer; winter) is when it has its downtime. I can imagine this being very pretty in winter - although fiercely cold I'm sure.
