|Antvorskov was the principal monastery for the order of Brothers Hospitallers of St. John of God, located in the current town of Slagelse on Zealand, Denmark.|
It was founded in 1165 by Valdemar the Great. Hans Tausen, who is credited as being a leading catalyst for the Danish Reformation, lived at the monastery and gave a sermon in 1525 that launched the reformation.
After the reformation, the buildings became a residence. In the 1700s, the buildings were sold and fell into disrepair.
In his autobiography, Hans Christian Andersen makes mention of excursions to the ruins of the monastery.
