The Knut Tower (About 1300)
In the Middle Ages the Knut Tower was known as the Canons' Tower and constructed as a crossfire tower on the north-western side. For a long period it was full of prisoners. In 1641 a horse-powered mill was build here, and the tower was later used as a powder magazine too. The name is a reference to the knight Knut Alvssøn, who was said to have lain unburied in the tower for 12 years after being killed by Henrik Krummedike in 1502. In recent times the tower has been partly reconstructed on the old walls.
