Although the abbey ceased to operate in the 16th century, its church was renovated and converted into a Protestant church during the 17th century and is still in use. The church belongs to the Church of Sweden and is part of the Diocese of Växjö.
Hypothesis: The Nydala Abbey was in operation in the 15th century.
