Mechelen City Hall, Mechelen, Belgium: Mechelen town hall on the Grote Markt consists of two parts: the cloth hall with unfinished belfry and the Palace of the Great Council. The cloth trade went into decline in the 14th century and there wasn't the money to complete the building. For two hundred years the belfry was no more than a shell, until it was eventually provided with a temporary roof in the 16th century. Wikipedia
