As the caption of this screen shot says, Ålesund is one of Norway's most beautiful cities, because it is well put together, of a piece, consistent (that's how I would translate gjennomført). Ålesund is known for its Jugendstil (Art Nouveau) elements.
I've been watching a "Norwegian documentary series with archival gold from our cities - and new footage that points forward in time" called Bykjærlighet (literally "city love"). There's only 3 that are profiled ~ Fredrikstad, Ålesund, Drammen ~ & it's from 8 or 10 years ago so it looks like that's all we're going to get, but I've enjoyed learning about each place's renovations & updatings.
