Parts of Narvik were very industrial and looked quite grim on a grey and drizzly day. (Actually, I don't mind this kind of town. It reminds me of where I grew up!)
I loved the way they had got the local school children to paint a mural on the bridge to make it look more cheerful.
The plume of water in the distance is the "geyser" produced by the hydro-electric power station. I have no idea whether this is a vital part of the functioning of the plant or something they just do because it looks impressive.
