Kegborg
Small ancient site with a round fortress mound from the Middle Ages.
Kegborg is offen mentioned in books about sights worth seeing and history. Fact is that there is nothing left from the castle and you can only see the spot very faintly, as a rounding in the grass.
However, a defensive tower was built here in the Middle Ages, in a good strategic location from which it was possible to control all access via the isthmus, Drejet to Kegnæs, and to monitor shipping traffic on Flensburg Fjord.
When Kegborg was built and what it looked like is unclear, but it was an important structure, as evidenced by the first known written mention of it in 1377, when the royal strongholds on Als were listed. Here, Kegborg is named alongside Nørreborg, Søndreborg and Brådborg on the Sundeved side.
A Bronze Age mound forms the basis of the fortification bank, and the earth that was dug away around it to create a moat was used to raise and expand the burial mound from a width of 19 to 23 metres in diameter. The lack of traces of the defence tower itself may indicate that it was built of wood, similar to the free-standing bell towers still known today, or that it was a half-timbered building.
An old legend tells that the fortress was built by Knight Kaj, who engaged in piracy by lighting fires on the hilltop where Kegnæs Lighthouse stands today. This misled ship captains into believing that there was a harbour, so they sailed towards the coast and ran aground, after which Andreas Kaj plundered them.
