This is a Gothic brick cathedral with roots in the 1300s, named after King Knud IV, who was killed in a wooden church east of the present building and canonised in 1101. Knud and his brother Benedict were buried in the church, which became a pilgrimage site in the late Middle Ages. The crypt holds six royal burials, including King Hans and Queen Christine. Queen Christine commissioned the altarpiece after King Hans died in 1513, and the Reformation was carried out in the church in 1532.
The church has many epitaphs, and touch screens inside tell its history. The entrance is wheelchair accessible, and there are toilets, including a gender-neutral one.
