During the second half of the 15th century, the castle was rented by Przemyslaus II of Těšín, who decided to reinforce the castle with the construction of surrounding walls.
În a doua jumătate a secolului al XV-lea, castelul a fost închiriat de Przemyslaus al II-lea de Těšín, care a decis să-l consolideze prin construcția de ziduri înconjurătoare.
