The ruined Kudryntsi Castle (Ukrainian: Кудринецький замок, Kudrynets'kyi zamok, Polish: Zamek w Kudryńcach) is perched on a hilltop overlooking the Zbruch River in Borschiv Raion, Ternopil Oblast, Ukraine, 25 km west of a larger fortress in Kamianets-Podilskyi. It was built in the early 17th century by Jan Szczęsny Herburt and throughout the ensuing century was subjected to repeated sieges by the Cossacks and the Turks. By the 19th century, some portions of the walls had crumbled away, and the structure was abandoned to its fate.
