The castle was built in the second half of the fourteenth century, probably by Sędziwoj Pałuka, staroste of Greater Poland, one of the closest associates of King Louis of Hungary and a beneficiary of generous granting of Sigismund of Luxembourg in Upper Hungary. However, it cannot be ruled out that Sędziwoj’s father, castellan of Rogoźno, Sławnik, has already begun building the castle. The first stage of construction would then take place in the years 1358-1360, while Sędziwój would only complete the construction of the defensive-residential building, which probably would have happened before 1398, when the unspecified construction works recently carried out at the castle walls were mentioned.
After the fire in the first half of the 17th century castle became the seat of Krzysztof Opalinski and was rebuilt to a early modern residence. Other changes took place in the eighteenth century under Maciej and Stanisław Mycielski. At the end of the eighteenth and early nineteenth centuries the building lost its importance, fell into ruin and unfortunately was almost completely demolished.
The castle was built on an elevation among the backwaters of the Gąsawa River and wet meadows. Access to it led by the bridge and the levee. It was built of brick on the foundation of glacial erratic stones. It was a 42×42 meter square with a recessed south-east corner. The residential and representative part of the castle was a tower on a square plan, with a side length of about 17.5 meters and a wall thickness of about 2 meters. It was not protruding from the face of the perimeter walls, but was strengthened by two diagonally arranged buttresses (of which the north-east probably hid the latrine). This may suggest that it originally had more than two or three floors above ground. In addition to the residential tower house, the castle consisted of a gatehouse and perimeter walls.
To this day, fragments of the peripheral walls have survived, whose height reaches up to 7 meters in the highest places. Entry into the ruins is free.
