The castle was built on the site of the early medieval slavic hillfort, circa 1304, by Głogów prince Konrad III, and was the local center of the princ administration. At the beginning of the 16th century, it was in the hands of the Brandenburg margraves and was the seat of their representatives. The first expansion of the castle was in the 15th century. The next was at the end of the 16th century. In 1633, the castle and the town were destroyed by fire. In the 19th century unused eastern and northern parts of the castle were demolished, rising at this place residential buildings.
The castle was built of bricks on a stone pedestal (which protected bricks against moisture of the ground). It was a compact, three-winged building with an inner courtyard, located within the town walls. Together with the town, it created a homogeneous defense system, but to protect castle against the townspeople, it was isolated from the town by a wall and a moat. Its oldest part was the massive tower preserved to this day. It was built on a square plan with a side length of about 10 meters. It received four storeys and a basement, accessible through the top opening in the vault.
The remains of the medieval castle are today four storeys of tower and basement walls of the west wing. Later reconstructions have obliterated the former communication system in the tower and the original shape of its window openings. A building from the 16th century adjoins the tower. In restored castle there are cultural institutions.
