Churches in older towns around the world were built on the monies of those who lived there. They were the fanciest buildings in town and they hold a lot of history. It is usually the first building you see as it had the highest peak, the steeple. We enjoyed checking out the many churches in the western area of Iceland where we traveled. I do not have the names of all the churches as many seemed to be set up on a farm, next door to the house. They ranged from very large to very small and most of the small ones you could not enter. I hope that you enjoy them as I did.
For more information, this site on the Iceland Churches is very informative.
