Construction of the tower began after 1241, raising it up probably
within the reconstruction of the castle burned by the Tatars. The
basement of the construction is the plinth of the stone blocks. The
construction was completed at the beginning of the fourteenth century -
but instead of stone hand-molded bricks were used . The tower is built
on a square plan with a side length of about 10 m, the thickness of the
walls on the level of courtyard is about 4 meters. The original
entrance to the tower is at now 10 m above the courtyard's level. The
external wooden staircase led there. Inside the tower there was a
dungeon without the outside exit and without the walking route inside.
Sometimes prisoners were kept there. During the Swedish wars the tower,
similary to the rest of the building on the castle hill, was destroyed
and for over 200 years remained in a state of ruin. At the beginning of
the 20th century, Karol Kaszny, then owner of the castle, conducted
renovation of the building. It was then supplemented with defects in the
wall of the tower and the upper level roofed pavilion. In the years
1928 - 1931 the castle was combined with a tower. In 2007 - 2010 the
maintenance works were undertaken on the tower. Currently the tower is one of the tourist attractions of the city, open for visitors.
