Adjacent to Marienkirche, Pfarrer-Ochse-Platz – named after the Siegen clergyman Wilhelm Ochse, who put up bitter resistance to the Nazi regime – is particularly evocative. 

To this day, the street names evoke former residents and the crafts they practised (tanners, butchers, etc.). These historic structures, lovingly restored in the 1980s, provide the backdrop to the Altstadtfest, the festival held every September.
