One can never get tired of Scandinavian windows and fresh berries with everything. Throw in a drunk communist viking as a guide and happiness is complete. Also, it's THE bridge. I managed to be unfazed by the Eiffel tower but had to hyperventilate over this one, yes I did.
When it's unbearably hot in 'temperate' Europe, you can either binge on lemonade and shove yourself in some overcrowded pool, or just fly up north, because it's so much cooler. And they have tiny cute stuff in their windows. And cinnamon buns.
