The Stork Tower is one of four surviving towers and other defensive structures originally built on the Chojna walls. It is also the only fully preserved shell tower in Chojna, which were built on a rectangular plan. As you might guess, its name comes from the massive nest built by generations of storks on the roof of the building; it functioned until the 1970s. For decades, the city walls were inhabited by the poor, who adapted the old, useless buildings into cheap apartments. In such surroundings, it is no wonder that the height of the walls decreased so drastically from the original 9m - to this day, traces of the use of demolition bricks can be seen in some nearby buildings. Due to its significant deviation from the vertical, it can be safely included in the group of original "leaning towers" in the current territory of Poland. It was caused by the drainage and leveling of the city moats in the 19th century, which caused the oak piles on which the tower is located to rot. Deprived of a solid foundation, it began to lean outwards, together with the adjacent wall.
The defensive walls with which the city was surrounded in the 13th-14th centuries have survived to this day in 50%, together with two gates and numerous lookouts.
