Oslo, Norway, is the capital of and most populous. Founded around 1000 AD, a trading post was setup in 1048 by King Harald III. It was elevated to capital city under Haakon V around 1300. I visited it during my world trip in 1995. The ferry from Copenhagen cruised into the harbor just at twilight. The view from the deck of the boat equaled (if not surpassed) the one in this poster. I stayed at summer university housing, found a nearby lake where nude bathing was allowed, and had great fun.
