The first brick castle was built in the 13th century, possibly after the town received city rights in 1275. Certainly already in the years 1283-1313 in the corner of the city stood the defensive residence of the Opole prince Bolesław I. It was owned by the Opole princes until 1532, when after the death of prince Jan II the Good, the Piast dynasty from Opole expired. Then it became the property of Zeidlitzs, and then Oppersdorfs, who were the owners of the castle until the Second World War. They also shaped the renaissance-baroque residence. In the 30s of the 17th century, a late-baroque reconstruction started, which caused the obliteration of the renaissance features. After the war damages, the castle was initially secured, but to this day there is no proper user, which causes its further destruction.
The exact appearance of the medieval castle is unknown. Probably it was a regular complex, whose core and the oldest part was a four-sided, stone residential tower with the dimensions of 12,8×16,6 meters, reinforced with four buttresses and surrounded by a moat. It was recorded in 1562, when the castle was dismantled and rebuilt, and it already had the form of a three-winged building. The stronghold was combined with the city walls. The new renaissance complex was also a three-wing castle with a outer bailey. In the second phase of the reconstruction, four, round, corner towers were erected. Then, before 1606, two wings were created, the northern and southern lower castle. The third phase of the development from the first half of the 17th century brought the full shape of the three-wing lower castle.
To this day, the upper and lower castle has been preserved, however, it underwent a baroque reconstruction, which obscured its renaissance appearance. Finding gothic elements is even more difficult. The building requires urgent renovation and development, but it is possible to visit it.
