In 1507, the complex burned in a fire, and two years ago, its reconstruction began. After ten years, the walls and the tower were strengthened. Since Rawa Castle was regarded as a modern fortress, in 1559 the so-called Rawa Treasure was placed here: the tax money needed to finance the regular army. Development of military technology made the complex obsolete by the mid-17th century. In September 1655, it was captured by Swedes during the Deluge. In 1657, before their retreat, Swedish soldiers blew up most of the complex; only the tower and fragments of walls remained. Soon afterwards, high ranking Swedish officer Pontus De La Gardie was temporarily imprisoned in the remains of the castle.
