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. 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. 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. 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. Klueting suggests that the shift in paternity coincided with the end of the double monastery, though a transitional period likely extended into the 1240s. 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. 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. Other donors followed their lead. In 1194, Conradus von Allagen and his heirs gifted their estate near Allagen for their salvation. Between 1207 and 1212, Lambert, dean of Paderborn, transferred his properties near
Neheim to the monastery. 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. 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. In the 14th century, Oelinghausen formed prayer confraternities with other monasteries and foundations, including Varlar,
Siegburg, St. Alban in Trier, and
Altenberg. 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. Beyond
choral prayer, the monastery supported a poorhouse and hospital, which received dedicated revenues by the 13th century. The hospital continued to operate into the late 15th century.
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. 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. 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. 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. 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. In 1548,
Archbishop Adolf III of Schaumburg conducted a visitation. The
prioress, a sister of
Landdrost Henning von Böckenförde gen. Schüngel, admitted that the monastic rule was only partially observed, with individual households being the primary issue. She noted no adherence to Lutheran teachings. Despite minor efforts to enforce the rule, individual households were not fundamentally challenged, and life at Oelinghausen increasingly resembled a secular canoness foundation. In 1583, troops under the Protestant-leaning Archbishop of Cologne,
Gebhard Truchsess, occupied the monastery. A secular administrator was appointed, and Lutheran preachers unsuccessfully attempted to convert the nuns. Most women fled to their families. After Gebhard’s defeat, the nuns returned, but the monastery had been looted, exacerbating existing financial difficulties. Under Kaspar von Fürstenberg’s leadership, a group of related nobles drafted new constitutions, proposing the abolition of the provost’s role and placing sole authority with the prioress. Fürstenberg secured the election of his sister, Ottilia von Fürstenberg (1585–1621), as prioress.
Revival and Transformation into a Canoness Foundation Over time, Kloster Oelinghausen had become a favored residence for Ottilia von Fürstenberg’s mother, evolving into a family hub, contrary to its constitutions. Ottilia’s brothers, Kaspar von Fürstenberg and Bishop
Dietrich of Paderborn, significantly contributed to the monastery’s financial recovery. Dietrich alone donated 4,334 thalers in memory of his mother for a memorial and sacramental foundation, with his total contributions reaching 10,000 thalers. These funds enabled the reconstruction of the abbey and the restoration of the provost’s office. Ottilia resolved property disputes, recovered lost assets, cleared 20,000 thalers in debts, and accumulated a surplus of 13,000 thalers. The monastery’s prosperity was evident in its ability to host the Archbishop of Cologne and the Bishop of Paderborn simultaneously, as noted in a visitation record. However, this period also saw raids by Dutch mercenaries, forcing temporary flight, and two plague outbreaks. Ottilia von Fürstenberg, also abbess of the Heerse Foundation, aimed to transform Oelinghausen into a canoness foundation, a goal facilitated by the internal weaknesses of Wedinghausen. Tensions arose after the 1613 election of Abbot Gottfried Reichmann, who sought to reintegrate Oelinghausen into the Premonstratensian Order. Much of the
Duchy of Westphalia’s nobility, led by the
Fürstenbergs, supported Ottilia. In 1616, Dietrich von Fürstenberg requested
Pope Paul V’s permission for the transformation. An investigation found no
monastic observance (“nulla regularis vigeat observantia”), with the women living without enclosure,
vows, or religious habits. In 1617, the Pope dissolved Oelinghausen’s ties to the Premonstratensian Order, and in 1618, it became a canoness foundation. A new constitution separated abbey and chapter assets, stipulating that, besides the abbess (as the head was now called), twenty canonesses would reside there. Ottilia’s successors continued this course.
Return to the premonstratensian order During the Thirty Years’ War, the canonesses repeatedly fled Oelinghausen. The Premonstratensians, rejecting the separation, sought to reclaim it. After a 13-year legal battle, Nuncio Fabio Chigi (later
Pope Alexander VII) ruled against the canoness foundation in 1641. Wedinghausen’s abbot forcibly reoccupied Oelinghausen, and the canonesses left with compensation. The monastery was repopulated by canonesses from Rumbeck Monastery. Financial recovery by the late 17th century allowed Provost Nikolaus Engel to build a new provost’s residence. Under Provost Theodor Sauter (1704–1732), a new convent building was erected, the church interior was lavishly decorated, and the organ was expanded.
Dissolution and Subsequent Use In the late 18th century, the rise of the Catholic Enlightenment in the Duchy of Westphalia and the Electorate of Cologne threatened the monastery’s existence. Wedinghausen conventual Friedrich Georg Pape prompted some nuns to complain about the provost’s authoritarian leadership and request a visitation. Maria Balduin Neesen, an Enlightenment advocate critical of monastic life, conducted the inquiry. He condemned “monastic despotism,” harshly criticized community members and clergy, and forced the prioress and cellarer to resign. The provost was deposed in 1789. Although Neesen unsuccessfully advocated converting the monastery into a welfare institution for bourgeois and noble women, the community remained internally divided. Younger nuns, influenced by ideals of freedom and equality, defied the prioress. In 1804, following the Duchy of Westphalia’s transfer to
Hesse-Darmstadt, the monastery was dissolved during
secularization. The estate was initially leased and purchased in 1828 by Baron von Fürstenberg of
Herdringen. In 1806, a
curacy benefice was established based on early modern Fürstenberg endowments, with the last monastery priest, Johann von Nagel, as its first incumbent. The independent parish of St. Petri Oelinghausen was founded in 1904. Today, it forms part of the Kloster Oelinghausen pastoral network alongside St. Antonius, St. Vitus Herdringen, and Heilig Geist Hüsten. From 1956,
Mariannhill Missionaries resided in Oelinghausen briefly. For over forty years, the church has hosted “musica sacra” concerts. The Baroque apostle figures were named Monument of the Month in Westphalia-Lippe in March 2014. == Structure ==
