We will be visiting Olso in early September. I was sad to learn the free guided tours are only offered June-August so we miss that opportunity by a few days. While they offer a way to sign up for paid guided tours, they are intended for groups of 30 and we are just 2 so the cost is prohibitive. I looked for a private/paid tour group including the City Hall interior but couldn't find any.
Is it possible to enter the City Hall building and see any of the murals and art work on your own?
Thanks in advance for your insights!
