In Wallenstein's time, the voluptuous daughter of the town judge, Anděla, used to meet the handsome executioner's page, Jan, in the Jičín Tower after dark. One night, when the judge discovered that his daughter was quietly leaving the house, he secretly followed her. In the local cellar, he caught the two lovers in a 'heated affair'. With a single blow of the judge's cane, the disgraced father knocked Jan to the ground and threw his lifeless body into the cellar well. The next day he took his licentious daughter to the convent in Chotěšov. After some time, when she had supposedly improved as a result of her pious upbringing, he married her off to a cloth merchant from Mladá Boleslav. However, the ghost of the lecherous John is said to still dwell in the well. He washes the cellar with bubbling water in an attempt to wash away his guilt and find eternal peace.
It is a fact that, until recently, mysterious flooding of the tower cellar still occurred from time to time. The last time was in 2013, when the water level rose to 82 centimetres. During the most recent reconstruction, a powerful self-priming pump was installed in the well and a drainage channel was created, which effectively prevents further supernatural rises in the water level.
