Oslo's Rådhus has become an iconic symbol of the city, ironic given that it's rather clunky & dated looking from the outside; to my mind, the two towers just aren't very interesting, just two big blocks of reddish brick with a clock on the side of one of them; but the charms of the Norwegian capital's City Hall are all in the details, both at the entrance to the Rådhus & inside. Henrik Sørensen's murals inside & the swan fountain in front of the building are worth a gander but to my mind, the wood carvings by Dagfin Werenskiold of scenes from the Poetic Edda that line the entrance to City Hall are the most compelling sight on a visit to the Rådhus. Best of all, in a very expensive city, the whole thing is free~! But the best view of City Hall from the outside is actually from the Akershus just outside the entrance to the Norwegian Resistance Museum, so definitely check that out if it's a sunny day.
