Kloster Wormeln, Cistercian monastery in Wormeln, Germany

Kloster Wormeln is a former Cistercian nunnery in the village of Wormeln, three kilometres south of Warburg. Its single-nave church, consecrated in 1315 to the Apostles Simon and Jude, stands alongside a convent building rebuilt in the early 18th century; the estate and other buildings are privately owned.

The complex was founded in 1246 by the sons of Count Albrecht III of Everstein and operated for centuries as a Cistercian convent. It was dissolved in 1810 when it came under the rule of Jérôme Bonaparte.

The church is dedicated to the Apostles Simon and Juda and was consecrated in 1315 by the auxiliary bishop of Mainz. The monastery's patron saints are remembered in the church's name, and the building remains the parish church of Wormeln after the convent was dissolved in 1810.

The monastery church remains active and is used for religious services, while the other buildings are now privately owned and used as agricultural facilities. Visitors should note that only certain areas are publicly accessible.

The monastery became the largest landowner in Wormeln through generous donations and acquisitions, which placed it at the center of the so-called Wormeln Monastery War in 1797. This conflict arose from disputes over labor obligations and taxes that local peasants had to pay.
