he king's castle existed in Inowłódz up to the 17 th century when it was damaged during so called "Swedish Deluge". It was a Gothic structure set on a rectangular plan with two octagonal corner towers, surrounded by a moat, raised by Kazimierz Wielki (Casmir the Great) in the 14th century. It was meant as a watchtower protecting the customs and a trade rout leading to Toruń. In the early 16th century the castle was developed and its fortifications strengthened. The extant walls of the basement and the towers and the outline of the moat have remained up to the present day.
