It was built at the turn of the 16th and 17th centuries according to Bernardo Morando’s design. In 1639 – 1651 the town hall was thoroughly remodelled by Jan Jaroszewicz and Jan Wolff.
The edifice was enlarged and made higher by adding three storeys with a high attic. The facades have Mannerist proportions, regular divisions and rich architectural décor. In the 18th century a guardroom and a fan-shaped double stairway supported by arcades were built in front of the town hall. In 1770 the town hall tower was topped with a slender dome with a lantern.
