The new hostess strengthened the high castle walls, three towers, billets, service premises and flasks. Ruling the region through her elders, Bona introduced a system of unbearable money and in-kind taxes on local people.

Having been discarded by the Italian, the castle nonetheless continued to maintain its patrol. For a long time no one was able to conquer this prominent building. In September of 1648 the troops of colonel Maksym Kryvonis besieged the castle. Severe battles between the Cossacks and Polish gentry continued for one and half months. Finally the stronghold was conquered and destroyed. Since then the castle has not been restored. At the Piatnytskyi cemetery under the hill the lime crosses on the Cossacks’ tombs grow white.
