Christianspris
Christianspris or "Frederiksort" was a Danish fortification somewhat north of the then Danish city of Kiel. In 1632 the Danish king Christian IV initiated the works of making a fortification on a land tongue on the West shore of the Kielerfiord on the Jernved peninsula. The purpose was to secure this land against German troops during the 30-years War. However , the town was short lived . Christian IV founded many towns and cities . It is thought this town only survived around 10 years .
