Oelinghausen Monastery, located in the Holzen district of Arnsberg, North Rhine-Westphalia, Germany, was founded around 1174 as a double monastery before transitioning into a Premonstratensian nunnery. In the 17th century, it was converted into a secular canoness foundation, but later reverted to the Premonstratensian order. The monastery was dissolved during the secularization of 1804.

The monastery church, dedicated to Saint Peter and the Virgin Mary, has served as a parish church since the dissolution. Predominantly Gothic in style, the church dates primarily to the 14th century, with its interior uniformly redesigned in the Baroque style during the 18th century. Notable features include the Kölsche Madonna, a statue from the early 13th century, and an organ with components from the 16th century.

Since 1992, the restored monastery buildings have been home to the Sisters of Saint Mary Magdalene Postel. A monastery garden museum has been established in recent years. The monastery and its associated estate are situated in a largely agricultural and forested area, distant from the nearest settlements of Herdringen and Holzen, within the Oelinghausen Landscape Protection Area.

Historical development Founding Period

According to traditional accounts, the monastery was founded in 1174 by Siegenand von Basthusen, a ministerialis in the service of the Archbishop of Cologne, and his wife Hathewigis.Founding charter, issued in Soest on May 29, 1174, by Archbishop Philipp von Heinsberg. Published in Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 3, pp. 22–23. The founders endowed the monastery with properties in Oelinghausen and Bachum. Years later, Siegenand made further donations and entrusted the monastery's advocacy to Count Reiner von Freusburg. After his death, he was buried in the monastery church.

Historian and archivist Manfred Wolf has recently questioned this narrative, arguing that the endowments by Siegenand were insufficient to sustain a monastic community. Wolf suggests that these were supplementary donations and that the actual founding occurred earlier, between 1152 and 1174. He posits that the Oberhof Oelinghausen, previously held by the Counts of Northeim and later by Henry the Lion, was transferred to Scheda Monastery, which then established Oelinghausen as a daughter house. Initially, only male religious lived there, with nuns joining later.Manfred Wolf: Die Gründung des Klosters Oelinghausen. In: Sauerland, March 2013, pp. 14–15.

This contrasts with the traditional view that women initially resided in Oelinghausen, later forming a double monastery where canons and canonesses lived in separate quarters within the same complex. Historian Edeltraud Klueting suggests that Oelinghausen was originally a women’s institution, with Scheda Monastery near Wickede providing pastoral care. Only after a period of consolidation did evidence of a double convent emerge. Such arrangements were not uncommon in early Premonstratensian history until the order’s General Chapter in 1188 mandated the separation of men’s and women’s monasteries. The double monastery structure in Oelinghausen persisted at least until the early 13th century, with references to “fratrum et sororum” (brothers and sisters) as late as 1238.Manfred Wolf: Bemerkungen zur Geschichte und Verfassung des Klosters Oelinghausen. In: Werner Saure (ed.): Oelinghauser Beiträge. Freundeskreis Oelinghausen e.V., Arnsberg 1999, p. 35.Edeltraud Klueting: Die Klosterlandschaft des Herzogtums Westfalen im Hochmittelalter. In: Harm Klueting (ed.): Das Herzogtum Westfalen. Vol. 1: Das Herzogtum Westfalen: Das kurkölnische Westfalen von den Anfängen kölnischer Herrschaft im südlichen Westfalen bis zu Säkularisation 1803. Münster 2009, pp. 81–84.

Oelinghausen was not independent; it was initially under the abbot of Scheda Monastery and, from 1228, under the paternity of Wedinghausen Monastery in Arnsberg. Unlike Rumbeck Monastery, Oelinghausen retained the right to freely elect its provost.Helmut Richtering: Kloster Oelinghausen. In: Magdalena Padberg (ed.): Kloster Oelinghausen. Strobel, Arnsberg 1986, p. 47.Charter of the Abbot of Prémontré and the General Chapter of the Order, 1231, in: Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 57, p. 44. Klueting suggests that the shift in paternity coincided with the end of the double monastery, though a transitional period likely extended into the 1240s.

Growth and prosperity The Archbishops of Cologne provided significant support to Kloster Oelinghausen. In 1174, Philipp von Heinsberg confirmed its foundation, exempted it from the parish of Hüsten in 1179, and granted it a tithe. After 1194, Adolf I. released the monastery from archdiaconal jurisdiction, donated a forest, and affirmed its existing rights and possessions. In 1208, Bruno IV. freed it from noble advocacy. Engelbert von Berg donated a revered statue of the enthroned Madonna and likely secured papal confirmation of the foundation from Pope Honorius III in 1225. The papal bull stated that the “prior and convent of Oelinghausen, the place, and those dedicated to divine service there, along with all their goods,” were placed under the protection of Saints Peter and Paul and the Pope himself, confirming all freedoms granted by the Archbishop of Cologne.

Following the archbishops’ example, numerous nobles and ministerials endowed the monastery. As early as 1184, Simon von Tecklenburg made donations. In the early 13th century, Adolf I. von Dassel and Hermann II. von Ravensberg contributed as well.Helmut Richtering: Kloster Oelinghausen. In: Magdalena Padberg (ed.): Kloster Oelinghausen. Strobel, Arnsberg 1986, pp. 46–47.

The Counts of Arnsberg were the monastery’s primary benefactors until the end of their rule. In 1204, Gottfried II. emerged as a key supporter, mediating disputes between the monastery and the Herdringen community.Helmut Richtering: Kloster Oelinghausen. In: Magdalena Padberg (ed.): Kloster Oelinghausen. Strobel, Arnsberg 1986, p. 47. Other donors followed their lead. In 1194, Conradus von Allagen and his heirs gifted their estate near Allagen for their salvation.Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 11, p. 26. Between 1207 and 1212, Lambert, dean of Paderborn, transferred his properties near Neheim to the monastery.Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 19, pp. 29–30. Despite its exemption from advocacy, the Counts of Arnsberg exerted significant influence over the convent’s life, even deposing an unpopular provost. As principal patrons, they expected good conduct and gradually assumed a quasi-advocacy role.Michael Gosmann: Die Grafen von Arnsberg und die „Vogtei“ über das Kloster Oelinghausen. In: Werner Saure (ed.): Oelinghauser Beiträge. Freundeskreis Oelinghausen e.V., Arnsberg 1999, p. 28.

In 1232, the first known provost, Radolf, secured the income from the Altenrüthen parish for the provostship, leading to decades of disputes with Kloster Grafschaft, which regained the rights in the 15th century. During Radolf’s tenure, Gottfried II. von Arnsberg also transferred patronage rights over the Hachen chapel to Oelinghausen.Helmut Richtering: Kloster Oelinghausen. In: Magdalena Padberg (ed.): Kloster Oelinghausen. Strobel, Arnsberg 1986, p. 48.

In the 14th century, Oelinghausen formed prayer confraternities with other monasteries and foundations, including Varlar, Siegburg, St. Alban in Trier, and Altenberg.Rudolf Krämer: Tod und Grablege, Heiligenverehrung und Reliquienkult in Oelinghausen (1174–1804). In: Oelinghauser Beiträge. Aspekte aus 825 Jahren Klosterleben. Arnsberg 1999, pp. 92–93. By the mid-14th century, a confraternity dedicated to St. John the Evangelist was established, admitting benefactors, donors, and local peasants. Noble and distant members held largely nominal memberships, with limited participation in religious activities. The confraternity maintained its own altar in the church, held property, and played a key role in funding the hospital. Its influence waned in the 17th century.Bernhard Padberg: Die mittelalterliche Bruderschaft St. Johannes Evangelist in Oelinghausen. In: Barmherzigkeit, Armenfürsorge und Gesundheitspflege im Kloster Oelinghausen. Arnsberg, 2017, pp. 10–17.

Beyond choral prayer, the monastery supported a poorhouse and hospital, which received dedicated revenues by the 13th century.Ingrid Ehlers-Kisseler: Die Entwicklung des Pitanz- und Pfründenwesens in den Stiften des Prämonstratenserordens. Eine Untersuchung der Fragestellung anhand der rheinischen und westfälischen Stifte. In: Irene Crusius, Helmut Flachenecker (eds.): Studien zum Prämonstratenserorden. Göttingen, 2003, pp. 453–454.Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 75, p. 50. The hospital continued to operate into the late 15th century.Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 791, p. 285.

Late medieval and early modern crisis

In 1391, the Archbishop of Cologne praised Kloster Oelinghausen for its diligent observance of divine services, noting it surpassed other monasteries. However, significant financial difficulties were evident. The archbishop exempted the monastery from the costly obligation of raising hunting dogs and condemned the migration of dependent peasants to towns and free territories, describing it as a “theft” that caused substantial harm. As lord of the Duchy of Westphalia, he prohibited cities in his jurisdiction from admitting these fugitives, declared granting them citizenship unlawful, and mandated heavy fines and forcible return to the monastery in chains.Charter of October 25, 1391, in: Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 497, p. 196.

Additional challenges emerged. There was a growing trend toward accumulating personal wealth and relaxing enclosure rules. In the early 15th century, the plague struck heavily, killing many nuns. The need to admit numerous young sisters prompted Archbishop Dietrich II. von Moers to emphasize strict enclosure. He decreed that “the young women who have taken the religious habit in Kloster Oelinghausen to serve God must not be distracted by frequent and unnecessary contact with secular persons,” prohibiting access to the inner cloister.Charter of February 5, 1437, issued in Cologne, in: Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 618, p. 232. These efforts were largely unsuccessful, with reports from the 15th century even noting a guesthouse operated by a Wedinghausen convent member.

The Soest Feud (1444–1449) brought significant economic burdens. During his tenure from 1483 to 1505, Provost Heinrich von Rhemen introduced the standard Premonstratensian habit, replacing previous attire. However, he failed to prevent the formation of individual households. To maintain external donations, the General Abbot permitted families to transfer secular goods for the nuns’ personal use in 1491, contrary to the order’s statutes.Hubert, Abbot of Prémontré, February 1, 1491, in: Manfred Wolf (ed.): Die Urkunden des Klosters Oelinghausen. Regesten. Fredeburg 1992, No. 792, p. 285. This further relaxed the monastic lifestyle. A shortage of priests hindered the provost’s liturgical duties, prompting the General Chapter of Abbots to call for more chaplains or canons.Circa 1555. Amid these challenges, Provost Gottfried von Ulfte resigned in 1539, leaving the position vacant for a decade. Regular worship could not be consistently maintained thereafter.
