At the instigation of the chancellor of the
Duchy of Jülich, Hermann von Brakel, the community of
Roermond Charterhouse in the
Duchy of Guelders were invited to set up a daughter house near the former ducal property of Vogelsang, about 1600 metres to the south of the town of Jülich. In accordance with the Carthusian tradition of Marian devotion, the new foundation was dedicated to the
compassion of Mary (; ). For the foundation Duke
William IV of Jülich and Berg and his first wife Elisabeth gave their property
zum Vogelsang to the Carthusian Order. Further endowments followed. The construction of the new monastery, for the usual Carthusian community of 12 monks, lasted almost 50 years, ending with the completion of the monastic church in 1527. During the
Reformation the prior was
Johannes Justus of Landsberg from
Cologne Charterhouse, who led on the necessity of a thorough spiritual renewal without going over to
Lutheran teachings. Through his many publications he became a significant figure in the
Counter-Reformation. Although the monastery was not economically as secure as was desirable, it did manage to attract further endowments and enjoyed the favour of the rulers. During the
War of the Jülich Succession (1609/10) the monastery, lying unprotected as it did on open ground in front of the fortified town of Jülich, was in constant danger. In 1609 and 1610 cattle, equipment and the church treasures were sent elsewhere for safety, and some of the monks and lay brothers sought refuge in other charterhouses, but the monastery itself suffered such plundering and destruction that for a time it seemed impossible that it could ever be made habitable again. In the
Thirty Years' War however it suffered little damage but on the contrary moved slowly from considerable poverty back to stable economic circumstances. In the second half of the 17th century under the priors Theodor Monheim and Antonius Basel the monastery enjoyed a golden age of prosperity, to which properly-managed forestry contributed, and was able to acquire gold and silver liturgical vessels and to invest capital at interest. Starting in 1696 the buildings were refurbished and the church decorated in the
Baroque manner. == Dissolution and after ==
