Gothic-renaissance tower was built in the years 1512-1519 by master Benedict of Sandomierz on the order of king Sigismund I the Old. Earlier there was probably a timber royal court with the tower of Casimir the Great. After the death of the founder, the castle lost its residential and representative functions, becoming only the seat of the parliament and then the municipal office. In 1657 it was destroyed during the fighting with the Swedes. After the war it was rebuilt, but gradually lost its importance. In 1869 the second floor was demolished and converted into an orthodox church. In the interwar years, the first restaurant took place, and after the Second World War it was rebuilt.
The royal residence was built on a mound surrounded by a moat. It was erected in the foundation part of the glacial erratic stones, and above of the brick. The corners and the buttress were faced with sandstone. This material also made window frames and portals. The tower was erected on a rectangular plan close to the square of 18×19,7 meters. It has high basement, ground floor and two floors. The lower storey housed the auxiliary storage rooms, while the upper storeys were of residential and representative character.
Today’s appearance of the tower is largely a result of postwar reconstruction. At present, the castle houses the District Museum with an exhibition of military, the history of the town and the castle, the prehistoric land of Piotrków and the renaissance and baroque interior furnishings.
