The relationship between the walled city and the suburbs was difficult and complex. Sometimes the suburbs were included in the division of the core city into city districts, sometimes the suburbs were districts in their own right. Thus, the suburbs were both a connecting and a dividing element. Based on the naming of the suburbs, the article also attempts to draw conclusions about the functions of these districts for the city as a whole: city gates, trade relations, trading orientation, but also confessional criteria were important for the naming. The suburbs were used multifunctionally by various actors, the city itself, but also the sovereign or monasteries appear as actors: Leprosoriums and hospitals were found there, the multifunctional fairground, but also monasteries were settled there. The suburb was also important for military defence - the former “glacis” later often turned into a city park or was densely built up. But the suburb was also a place of leisure culture, fireworks and inns, but also increased crime had their place there.
