Antvorskov

Antvorskov Monastery was the principal Scandinavian monastery of the Catholic Order of Saint John of Jerusalem, located about one kilometer south of the town of Slagelse on Zealand, Denmark.It served as the Scandinavian headquarters of the Order, known also as "the Hospitallers", and the prior of Antvorskov reported directly to the great officer of the Order in Germany, the Grand Master of the Order on Rhodes, and the pope. As a result, Antvorskov was one of the most important monastic houses in Denmark. Before the Reformation, its prior often served as a member of the Council of State as well.
