Grafschaft Glatz
Under Sigismund of Kauffung, the castle again became a hideout for robber barons. In 1501, Ulrich of Hardegg bought the County of Kladsko/Glatz, including the Lordship of Hummel. In 1537, his son pledged it to John III of Pernstein, whose son Vratislav II of Pernstein inherited the Lordship in 1548. In 1459, the County of Kladsko/Glatz, including the Lordship of Hummel, was sold to Ernest of Bavaria of the House of Wittelsbach. On 10 December 1459, Ernest gave the Lordship of Hummel to his illegitimate son Eustace. In 1550, Eustace was ennobled by Emperor Charles V as "Eustace of Landfried". Eustace was legitimized as a noble son of Ernest by Pope Julius II. Eustace sold the Lordship after Ernest's death to Ernst Gelhorn von und zu Alten Greckau und Roge. In 1590, the Lordship was acquired by Rudolf of Stubenberg, who pledged it to the city of Reinerz (present-day "Duszniki Zdrój") in 1595.
