In Wallenstein's time, the voluptuous daughter of the city's 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 went after her in secret. In the local cellar he caught the two lovers "engaged with each other heatedly". With a single blow of the judge's staff, the disgraced father knocked Jan to the ground and threw his lifeless body into the cellar well. The very next day he took his licentious daughter to the women's monastery in Chotěšov. After some time, supposedly already improved by the pious upbringing, he married her off to a cloth merchant from Mladá Boleslav. However, the spirit of the lecherous John is said to still dwell in the well. He washes the cellar with water with bubbling moaning in an attempt to wash away his guilt and thus attain eternal peace.
It is a fact that mysterious floodings of the tower cellar still occurred from time to time until recently. The last time was in 2013, when the water level rose to 82 centimetres. During the last 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.
