 Between the 15th and 17th centuries the Korets Castle was the seat of the princely House of Korets that issued from Duke Narimantas of Volhynia.After the death of the last Prince Korecki in 1651, it passed through inheritance to the junior line of the House of Czartoryski and became its main seat until the line died out in the early 1800s.Following the 1569 Union of Lublin, Korets became part of the Kingdom of Poland, where it remained for over 200 years, until the Partitions of Poland.
