Lutsk Castle (Ukrainian: Луцький замок, romanized: Lutskyi zamok; Polish: Zamek w Łucku), also locally known as Liubart's Castle (Lithuanian: Liubarto pilis; Ukrainian: Замок Любарта, romanized: Zamok Liubarta) or Upper Castle (Lithuanian: Lucko aukštutinė pilis; Ukrainian: Верхній замок, romanized: Verkhnii zamok), began its life in the mid-14th century as the fortified seat of Gediminas' son Liubartas (Lubart), the last ruler of united Galicia-Volhynia. It is the most prominent landmark of Lutsk, Ukraine and as such appears on the 200 hryvnia bill. (Another city castle, called Lower Castle, built by the Czartoryski family since the 14th century, is now a ruin).
