Sittichenbach Abbey (Kloster Sittichenbach), sometimes also known as Sichem Abbey, is a Cistercian monastery in Sittichenbach, now part of Osterhausen near Eisleben in the Mansfeld-Südharz district, Saxony-Anhalt, Germany.
The abbey was founded as a daughter house of Walkenried Abbey in 1141 by Esiko II of Bornstedt, under the first abbot Volkuin. The new foundation rapidly acquired extensive lands on which to establish farms. In 1180 monks from Sittichenbach, at the request of margrave Otto I of Brandenburg, established Lehnin Abbey. Later foundations were Buch Abbey near Leisnig (1192) and Grünhain Abbey in the Erzgebirge (1235).
In 1346 the abbey suffered greatly from a feud between Ludwig von Meißen, Bishop of Halberstadt, and the Count of Mansfeld. The abbot and monks were taken hostage and treated so harshly that several of them died. The Count of Mansfeld was excommunicated as a result of this incident.
From this time onwards the abbey premises were used for local government purposes. Amt Sittichenbach passed in 1656 to Saxe-Weissenfels and from 1686 to 1745 to the Principality of Saxe-Querfurt, after which it was included in the Electorate or Kingdom of Saxony. It was incorporated into the new Prussian state in 1815.
After the reunification of Germany in 1990, the lands and remaining buildings were returned after nearly 500 years to the Cistercian order. They have done much restoration, including a very creative re-building of the chapel which is used for daily prayer. Other buildings have been added and restored so that the site has become a hotel and retreat centre. An open field has been developed into a beautiful area for meditative walks which includes gardens, worship spaces, shrines and a labyrinth.
There are a few remains of the original abbey buildings still to be seen: among them are the abbots' chapel, the fishpond and the dovecote.
