The stately building complex in the architectural style of the High Renaissance was built in 1587-89 using older components. On the market side of the three-storey façade there is a risalit in the middle and on the side a stair tower with a substructure of two floors and a towering, octagonal attachment, at the beginning of which there is a covered gallery. The tower is covered with a curved dome crowned with an open lantern. The roof was restored after a fire in 1633 without the original high dormers. A flood in 1661 caused severe damage, and reconstruction began in 1667. In the 19th century, a short wing of the building was erected to the west. In 1928/29, the town hall was expanded to include the north wing of the building, with the exterior being adapted to the Renaissance building. In 1969 the exterior was renovated. The stair tower was repaired in 1991. On the ground floor there are portals from the time of construction. On the facade north of the stair tower at the height of the first floor is the portal to the former council scales, which is no longer accessible. The groined vaults of the former council scales and the neighboring rooms in the main wing were renovated or re-used in 1904. The balance beam of the old council scales is now housed in the vestibule. On the second floor are the hallway and the living room.
