These include one of the city’s symbols - a monumental tower (beffroi - a castle watchtower or city belfry in the form of a free-standing tower or attached to the city hall building) from the 13th-15th centuries, with a carillon (an ensemble of tower bells on which the melody can be struck with the hearts of bells using a special keyboard) consisting of 47 bells. The tower is located on the Grote Markt market square. Next to the belfry are market halls from the 13th-15th and 16th centuries.
