Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

I still don't recognise it...but there you go, it must be right if Wikipedia says so...  The back of it, I suppose...and photo taken with a special lens?

What do I know? I just followed the image address...
I've never been to Oslo. The only places I know in Norway are Stavanger and the North Sea oil/gas rigs...

Could be a polarizing filter.

What does that do? I know nothing about photography...

The propagation of light can be seen as a series of blips, where energy expands and contracts around a line that is the direction of propagation. You could visualize it as an expanding and contracting blob that is symmetrical around the direction of propagation.  This can be considered as being composed of vertical and horizontal variations.  A polarizing filter only allows  light to pass in one axis, say vertical.  With two polarizing filters, one of which can be rotated, you can  have anywhere from half of the light getting through, when both filters are set to the same angle to none of the light getting through, when one is set to horizontal and one to vertical.  Get such a filter at a photography shop and try it. It is neat.

Glare is mostly caused by the light that is in only one of the planes.  If you put a single filter on your camera and look at the image while rotating the lens you will see dramatic effects.  Most photography that has dramatically blue skies is the result of such use of polarizing filters.  Learning to use polarizing filters can have a dramatic impact on the quality of landscape photos.  You don't have to understand the physics of light to use it.  I hope my explanation is comprehensible.  Mig could probably improve upon it.

It's been discussed, from the photography point of view, in several of the Friday Photo Blogs.

Funny. I have been to Oslo only once for three days, but I recognised it. Which recalled a faint memory. I must have seen it from the back when coming down from the camping place towards the inner city, but checking on Google Maps, I realised and recalled that that was because we lost our way... (As an excuse, the map wasn't in my hand.)

Ha, that's probably because you had no females in the group or did not listen to them. :-)

The map was in the hand of a female :-)

Even funnier to quickly find where we got lost more than a decade later (here, missing the continuation of Sørkedalsveien and going for Fridtjof Nansens vei instead, eventually ending up behind the palace). Also didn't remember that the camping place was just of the foot of Holmenkollen.

Should visit Scandinavia again. Sometime...

It is indeed a picture of the Norwegian Royal palace in Oslo, viewed from the park in the "back". The idea came from my recent holidays in northern Europe, but I was basically just testing Eurotrib. I published another image, which didn't seem to work, for one reason or another.
