The Castle in Siewierz was built in the first half of the thirteenth century on a man-made hilltop, where formerly stood a wooden fortress. The oldest of the stronghold's fortifications come from the fifteenth century. In 1443 Duke Wacław I of Cieszyn sold the town and the castle to Kraków's bishop Zbigniew Oleśnicki. The Bishops of Kraków expanded the castle and its fortification walls. The castle began to crumble in the seventeenth century, and Swedish raids quickened its deteriorating. After The Deluge the castle was rebuilt by that didn't stop it from deteriorating and turn into a ruin. The last resident of the castle, Feliks Paweł Turski, left the residence in 1800. The only reason the building did not diminish is due to extensive reconstruction and renovation works in the 1950s, 1970s, and 1990s.
