It is a city castle in its nature, incorporated into the system of Bielsko fortifications from the beginning, at the same time providing their strongest section. Over the centuries it performed the function of a Silesian border-stronghold, first guarding the borders of Cieszyn and Oświęcim district duchies and then in the second half of the 15th century it protected the Czech and Polish state border and from 1526 - the Austrian-Polish border. Starting from the close of the 16th century, its defensive role was declining and the Castle gradually transformed into a nobleman’s mansion.
