Octagonal, 32 meters brick tower is the only remnant of the castle built in fourteenth century by the king Kazimierz The Great. There are 109 stairs leading to the top – at first running outside the structure, and from the top of the defense walls – inside the structure. From the peak one can admire a great view at the Gopło lake and its area.
There is an interesting legend associated with the king Popiel, who was eaten by mice. It says, that the king – reluctant to the advice of the council of his uncles - did not prevent a tragedy and let his wife – Gerda – poison his guests during a feast. From the bodies, hidden in the castle, thousands of mice were born, before which the king and his wife escaped and found shelter in the tower. Mice has crossed the lake, though, and bit the royal couple to death.
Remembrance of the legend of the evil king Popiel adds a thrill of excitement during climbing to the tower. From the more realistic facts, one tells about 14 cannonballs still residing in brick walls, which are the remains of Polish-Swedish war. Supposedly under the tower there are walled basements and passages connecting the former castle to the parish church.
