Around 1080, a building was constructed to the north of the first travertine cathedral known as Kloster for Brødrene (Friars' Cloister) which was no doubt used as a school house.

[2] After the Reformation in 1536, the school was struck by a period of poverty, forcing the pupils to beg in the neighbourhood for food and clothing.

The curriculum did not change until the 18th century when it was adapted to include both theology and law, attracting more pupils.

[3] A new building for the school was completed on the cathedral square in 1842 to a design by Jørgen Hansen Koch.

[6] The school provides a high level of secondary-school education thanks to its competent staff and a pleasant teaching environment designed to motivate pupils on an individual basis.
