Why it belongs here
The Dubno Castle (Ukrainian: Дубенський замок, romanized: Dubens'kyi zamok; Polish: Zamek w Dubnie) was founded in 1492 by Prince Konstantin Ostrogski on a promontory overlooking the Ikva River not far from the ancient Ruthenian fort of Dubno, Volhynia. Ostrogski castle was rebuilt in stone in the early 16th century under the Lithuanian rule when the city was part of the Grand Duchy of Lithuania.
