Kärnan

Kärnan (; da, Kernen, both literally ''The Core'') is a medieval tower in Helsingborg, Scania, in southern Sweden. It is the only part remaining of a larger Denmark, Danish fortress which, along with the fortress Kronborg on the opposite bank of the Øresund, controlled the entranceway between the Kattegat and the Øresund and further south the Baltic Sea.''Kärnan'' (Helsingborg.se)

History

The origins of the Helsingborg fortress are disputed. 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 (Denmark), Zealand.

It was surrendered to Sweden along with the rest of Skåneland as part of the Treaty of Roskilde in 1658. The fortress was retaken by Danish forces in 1676 during the Scanian War, and its capture celebrated by flying a giant Flag of Denmark above it. This flag was later captured by the Swedish army and is preserved in the Armémuseum, Army Museum (''Armémuseum'') in Stockholm. The fortress returned to Swedish control by the Treaty of Lund in 1679. Charles XI of Sweden ordered most of it demolished fearing that it was too exposed to a sneak attack from Denmark. The only thing that was saved for posterity was the old medieval tower core. The tower continued to serve as a landmark for shipping through Øresund.

Restoration

The castle was restored starting during 1893–94, under instructions from Oscar Ferdinand Trapp, a Swedish businessman and engineer (1847–1916). Architect for the restoration was Josef Alfred Hellerström (1863–1931), Helsingborg city architect from 1903 to 1928. The objective of the restoration was to restore, to the extent possible, the appearance the structure had based upon the oldest known medieval illustration. The building's crenellation dates from these repairs.
