Bryon LeRoy Godbersen is the originator of this amazing town. Bryon is from a local farm family and married his high school sweetheart. But, this midwestern farm boy went on the excel as an inventor and in industry.
He also loved castles, so he built them, everywhere. There is a castle skate palace, gates into the city, a bride across a stream in the golf course. There are also private homes built as castles, the town's shopping center, and newspaper office all looks like castles!
Knights flank the gates. This is certainly worth a detour to experience
This is a very interesting town, the castle influence came from Bryon
