Mariawald Abbey () was a monastery of the Trappists (formally known as the Cistercians of the Strict Observance), located above the village of Heimbach, in the district of Düren in the Eifel, in the forests around Kermeter, North Rhine-Westphalia, Germany. In September 2018, the last remaining monks left Mariawald Abbey and the monastery is currently up for sale. History Cistercians Following Heinrich Fluitter's vision of the Blessed Virgin Mary, a shrine and chapel were built on the site of it, which became a place of pilgrimage, the Marienwallfahrt. For the proper care of the site and the pilgrims land was given in 1480 to the Cistercians of Bottenbroich Abbey, who established a priory here, which they were able to move into on 4 April 1486. The new monastery took its name from the shrine to Mary and from the woods in which it was situated: "Marienwald", or "Mary's wood" In 1795 the monastery was closed as a result of the French Revolution and the monks were expelled. The image of the Virgin was removed to safety in Heimbach. The priory buildings were abandoned and allowed to fall into decay. Trappists In 1860 the priory was re-settled by Trappist monks from Oelenberg Abbey in Alsace. From 1875 to 1887 the monks were exiled because of the Kulturkampf ("cultural conflict") policies of the Imperial German government. In 1909, Mariawald was raised from the status of priory to that of an abbey. The monks had to leave the monastery yet again under the Nazi regime during World War II, from 1941 until April 1945, when the surviving members of the community were able to return. The monastery had to be largely rebuilt, because it had been seriously damaged in the war. After World War II, a brewery was run at the abbey until 1956 when beer production ceased, in part due to availability of water and brewing ingredients. Present day Mariawald Abbey is the only extant men's Trappist monastery in Germany. The monks follow the Rule of St. Benedict and the constitution of the Cistercians of the Strict Observance. Visitors can also stay a few days in the abbey's guesthouse, but the parts of the monastery used by the monastic community cannot be visited. The abbey runs a tavern and bookshop. It also produces and sells its own liqueur. In 1997 it was one of eight Trappist abbeys which founded the International Trappist
