You can tell Helsinki is a port city. Like I said in earlier posts, they have a lot of beautiful detail in their older buildings. The oldest have a lot of tiny nautical themed details. For fairly typical example there are what appear to be a pair of salmon on the moldings of the windows at the office.
My favorite so far though is this building that has barnacles under the eves. Its so subtle that from a distance it just looks like a turbulent pattern of bumps.
Then when you look closer you can see it is incredibly detailed. Someone had a lot of fun with this, and it was done long enough ago to have been a hell of a lot of work.
