Przewodziszowice Castle - brick fortress ruins, located on the peripheries of the former village of Przewodziszowice (now part of the town of Żarki), on the Kraków-Częstochowa Upland.

The fortress was raised in the fourteenth, or on the turn of the fourteenth and fifteenth-century, as commanded by the Polish monarch Casimir III the Great, or Silesian duke Vladislaus II of Opole.

[1] Together with the Suliszowice Fortress, the fortresses served as a propounded flank of what now remains of the castle ruins located in the small forest osada of Ostrężnik Gmina Janów.

In the fifteenth-century, the castle reserved as the residence for knight-highwayman Mikołaj Kornicz Siestrzeniec, known as "Siestrzeniec".

According to a legend, the knight hid his loot in stone fissures or the castle well.
