Why isn't it plumb?
It’s plumb by *magnetic* North. 😉
Most likely to handle getting smashed by ice sheets. If you notice the ladder on the side it is tilted away from is busted (they were lifted up), that is probably the direction the ice comes from (it is in these shots). So as the ice rides up the structure and breaks around it, it will do less damage to the structure then if it was plumb.
My guess would be that it was vertical, originally - notice that the walkways are also tilted. Moving pack ice has an incredible amount of force behind it, and this has seen 90 years worth of the seasonal pack and ice-break...
It was built straight and plumb, there are older photos taken prior to the damage that show that.
The amount of sea level rise is scary.
Interestingly, this part of Scandinavia is experiencing springback from the loss of the weight of the now melted ice sheets from the last ice age. The land is actually rising up out of the sea.
