The Ostroh Castle began in the 14th century with the Brick Tower. Tower-donjon (residential and defense zone). It is located in the south-east of the hill. It acquired its final form at the end of the 19th century. Currently, it is a three-story brick building, rectangular in plan. Its 30-meter walls are reinforced with buttresses. Supplies were stored in the lower tiers of the tower, and princely rooms were located in the upper tiers. A well was also dug in the depth of the tower. #Castle
