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.

After Jakub Ludwik Sobieski's death in 1737, the castle passed to the Radziwiłł princely family and then (in 1801) to Count Łukasz Komarnicki-Pawlikowicz (of the House of Sas), whose heirs sold it to the Austrian crown in 1834.

Thousands of people belonging to the Jewish faith were taken from Zolochiv and were killed by the Germans at the outbreak of Operation Barbarossa.

Exhibits include more than 25 European coats of arms, dinosaur bone chandeliers, and a replica of a typical royal crown from the 13th century, that could be similar to that of Daniel of Galicia.
