During my Europe trip in February/March 2016, I visited some friends in Norway for a couple days, in a cute little town called Tønsberg. Despite the freezing temperatures and very deep, wet snow, I found it to be incredibly relaxing. It was a nice escape from the city. There was such an interesting mix of architecture - even in a small rural town there were some excellent examples of Functionalism (for architecture nerds out there).
I REALLY hope to go back in warmer weather and explore the forests, as I hear they are rich with flora and fauna.
I didn't do as much site-seeing as usual when I was there, because of the harsh weather, but I made sure to explore at least a little!
