Kärnan, the medieval tower, Helsingborg, Sweden >> HFF - HAPPY FENCE FRIDAY

Kärnan is a medieval tower in Helsingborg, Scania, in southern Sweden. It is the only part remaining of a larger Danish fortress which, along with the fortress Kronborg on the opposite of Øresund, controlled the entranceway between Kattegat and Øresund and further south the Baltic Sea.

The origins of the Helsingborg fortress is disputed but Danish legend places its origin to the reign of the legendary King Fróði. However, this legend has not been supported by archaeological proof. Dendrochronological dating has shown that the core was built in the 1310s, when Eric VI of Denmark was King of Denmark. It was considered the most important fortress in Denmark, and was integral in securing control over the strait between Scania and Zealand.
