Studying in Halden
I studyed in Halden to get my Norwegian equivalent to an BSc degre. I lived there for four years, from 1998 to 2002 while doing computer science and one year. The univeristy, Høgskolen i Østfold, is a great place study. Courses are good and the size is perfect. Not too big so you feel lost, and not so small that you know everybody within the first week.

"Living in Halden"
For the last three years in Halden I lived at a student house called Os Plaza (sounds quite fancy, doesn't it :). For great Plaza-pictures, look at Magne's Plaza site:
Well, there is not a whole lot to see, besides the old fortress, which is in fact worth going to Halden for, if you're in the region.
