Dubenskyi Historical and Cultural Reserve

One of the most notable sights in Dubno is the Dubno Historical and Cultural Reserve — the Castle Complex. Surrounded by a moat, the high walls became a real barrier for those who tried to get through its walls. Careful planning and thoughtful architecture allowed the complex to survive to this day. The complex includes a bridge; crossing it takes you to the gatehouse. Bastions with towers stand on both sides of the grounds. Along the northern wall are the palace of the Lubomyrsky princes (18th century) and the palace of the Ostrozky princes (16th century).

The Castle of the Ostrozky princes is the city's most important building, once belonging to Ostrozky — the richest man living in Ukraine. Had it not been for his Orthodox faith, he could have become the next king of the Polish-Lithuanian Commonwealth. According to legend, all the underground rooms of the Ostrozky Castle contained the most valuable items. Today, however, these are the scariest places, where a torture museum has been set up.

Because of Yuzefa Lubomyrskyi's passion for gambling, in the 19th century the castle complex was sold to the military authorities. Today its grounds are a historical and cultural reserve with the character of an entertainment venue. Theatrical performances, tours and film screenings are held here in a fitted-out cinema.
