In 1482 it became property of Matthias Corvinus of Hungary for a short time; in 1487 Hans von Königsberg received the castle from Emperor Frederick III.

On that occasion the ring of bastions was erected in order to change the castle into a refuge.

In 1604 castle Bernstein was unsuccessfully besieged for weeks by a combined army consisting of Hungarians, Turks, and Tatars under the leadership of Stephen Bocskay.

Due to an explosion of the gunpowder storeroom, in 1617 Ludwig Königsberg ordered the rebuilding of the Gothic inner part of the castle in Baroque style.

A short time later (1644) Ehrenreich Christoph Königsberg sold the sovereignty and the castle to Count Ádám Batthyány.
