Nütschau Priory (in German Kloster Nütschau or Priorat Sankt Ansgar) is a house of the Benedictine Order located at Travenbrück near Bad Oldesloe, Stormarn, Schleswig-Holstein in Germany.
Around 830 a castle was built on the Trave, surrounded and secured with an earth wall: the Nütschauer Schanze, part of a Carolingian fortification.
In 1577 Heinrich Rantzau built the small moated castle, the "Castrum Nutzkow".
[1] The Benedictine house originated after World War II as a refuge for displaced persons, particularly Catholics from the former German territories.
In 1965, Bishop Helmut Herrmann Wittler donated an Ansgar reliquary to the Nütschau monastery.
