In 1919, the first Redemptorists came to Heiligenstadt in Eichsfeld and established their first branch in 1920 with the St. Klemens House. In 1925, the foundation stone was laid for the current St. Klemens monastery and the church of St. Gerhard. The main task of the monastery branch was the parish mission, but also pastoral care in confession. During the last years of the division of Germany, the monastery was directly subordinate to Rome, as direct cooperation with the Cologne province was no longer possible. The monastery building has an important theological library in a multi-storey hall library with two galleries and a separate monastery chapel. St. Clement's House, built as a transitional building, was used as a retreat house after the monastery moved in.
