Eastern Norway most people are working in service-oriented companies. The coastal area is varied, from the metropolitan Oslo to the more quiet and idyllic old maritime city of Drøbak, and the oldest city in Norway, Tønsberg There is also some museum railway lines, for example the Krøder Line, where one can ride heritage steam and diesel trains on old twisty railway tracks. Oslo, the capital of Norway, has attracted people from all over Norway. Most of the immigrants settle here as well. There are numerous mosques, Hindu shrines, Sikh temples, Buddhist temples, as well as many churches, giving Oslo a cosmopolitan feel.
Olaf II of Norway together are both traditionally regarded as the driving forces behind Norway's final conversion to Christianity. However, large stone crosses and other Christian symbols suggest that at least the coastal areas of Norway were deeply influenced by Christianity long before Olaf's time; with one exception, all the rulers of Norway back to Håkon the Good (c. 920–961) had been Christians; and Olaf's main opponent, Cnut the Great, was a Christian ruler. What seems clear is that Olaf made efforts to establish a church organization on a broader scale than before, among other things by importing bishops from England, Normandy and Germany.
