I am not sure what type of church / church community house this is, but when I passed I got the feeling that it might be more international inside here, than in an ordinary Norwegian church.
I am not a church goer, but still a member of the Norwegian Church like most people are here in Norway.
The number of church goers has gone down. There are probably lots of reasons for that.
I read in a report that Greeks are the people in Europe who go most frequently to church.
