Sorø Abbey was the preeminent and wealthiest monastic house in all of Denmark during the Middle Ages. It was located in the town of Sorø in central Zealand. After Denmark became Lutheran in 1536, the abbey was confiscated by the Crown. The abbey was turned into the Sorø Academy in 1623, an educational institution that has served as a knight academy, a venue for higher learning during the Danish Golden Age. It survives to date as a boarding school.
