Zolochiv Castle was a residence of the Sobieski noble family on a hill at the confluence of two small rivers in the south-eastern part of Zolochiv, Galicia.
The rectangular fort was built in 1634-36 by Jakub Sobieski using the labor of enslaved Crimean Tatars. The Sobieski castle comprised solid walls in a then-current Dutch style, with four pentagonal towers at each corner, and the so-called "grand palace". The Chinese Palace, a diminutive mauve-colored rotunda flanked by one-storey wings, was added later in the century as John III's gift to his French-born wife, Queen Marie.
In 1672, the castle was taken after a 6-days siege by the Turks under Kapudan Pasa. Three years later, it survived a new siege by the Ottoman army. After Jakub Ludwik Sobieski's death in 1737, the castle passed to the Radziwiłł princely family and then to Count Łukasz Komarnicki-Pawlikowicz, whose heirs sold it to the Austrian crown in 1834.
In the 19th century, the castle was adapted for use as a hospital and barracks. It was turned into a prison in 1872 and continued in use after the September Campaign. There's a chapel commemorating the victims of the NKVD on the grounds of the castle.
