The Old Town Hall is a classic merchant edifice erected in 1827. Its architect – a merchant by the name of Jacobi – rebuilt the whole western quarter of the square after the 1826 fire. In 1847, the town authorities purchased the building and adapted it for a town hall, adding an oak clock tower. In 1867, the town purchased an adjacent building (which now is a museum) and made a mayor’s home in the second floor. The first floor was set aside for the offices – namely, a court and a bailiff offices. Sleeping rooms were arranged in the town cellar, the western part of which in early XX century became a town hall beer parlour. The building continued as town hall until 1924.
Housed the Regional Museum between 1926 and 1952. Provided communal housing from the museum closure until 1998. Upon a thorough renovation, from October 25, 2004 houses the museum and the Wedding Palace.
