[1] As part of Bismarck's power struggle (Kulturkampf) with the Roman Catholic Church in Germany, monastic orders had been forbidden to accept novices.

When the war ended, in late 1918, the monks decided to relocate to a site closer to the frontier with Germany, choosing to build on farmland half a kilometer outside the hamlet of Mamelis, in the southern part of Limburg.

In 1927 Dom Romuald Walters affiliated the new Abbey to the Beuronese Congregation, which was then in a particularly dynamic phase, notable both for theological research and in respect of involvement with the modernisation of Gregorian liturgy.

Liberation in September 1944 brought no respite for the German monks in Limburg who were initially interned and then expelled to what remained of Germany.

The monastery buildings were occupied by the American Army, later being used to house "political delinquents" and returning Dutch refugees from Indonesia.

Just one monk, having Dutch citizenship, was permitted to remain within the walls of the monastery, and he prevented the total pillage and destruction of the monastic records, but most of these nevertheless disappeared.
