Duborg Castle

There is uncertainty about the etymology of Dyborg. One theory suggest that it was named after a Danish knight called Jens Due, who lived in the 16th century. Another explanation is that a dove () may have been included in the castle's coat of arms and thereby given its name. == History ==

The castle was erected by Margaret I of Denmark and Eric of Pomerania, and would take five years to build, even continuing on parts of the fortifications after Margaret's death in 1412. Built as protection against the Holsteinians, Duborg would serve an advantageous location in relation to attacks from the west, while the harbor could be defended from the castle. == See also ==
