Under Hammerspach's successor, Hans von Zwingenburg, the well piping was replaced in 1510/12 and building damage repaired. But the next superintendents, Nikolaus Mathias and Peter von Rada, complained of serious shortcomings. In 1547 the castle-guard was taken over by Christian Schwärzel. The construction work started by him was continued, after an interruption, by his successor in 1560, Alexander Gabelowitsch né Sandri. During the invasion of Tyrol by Elector Maurice of Saxony the castle was in good defensive order. It was not captured, but its own soldiers lost a lot here. In 1560 another new superintendent was appointed, Martin Fuchs, who also made a lot of complaints about the poor state of the building to the state treasury. These ended under the next incumbent, Johann Gwarientis (from 1569), because Archduke Ferdinand of Tyrol underwrote the castle in 1586 with all the estate of the parish of Seefeld. The priest was incorporated in 1604 into the Augustine hermitage monastery in Seefeld and there was no longer a warden living in the castle itself.
