Bottmühle (Köln)

The Bottmühle stands in Cologne’s southern old town, a round four-storey stone tower that once turned grain into flour. It sits on a raised patch of ground beside a steep grassy slope where a 60-metre stretch of the medieval city wall still rises. The street An der Bottmühle loops around the base, marking one of four mills built along or on the old fortifications. The mill’s story begins with Alessandro Pasqualini, the Italian military engineer who strengthened Cologne’s defences in the 16th century. In 1587 the city council hired Peter von Gleuel, trained in Holland, to erect a wooden windmill on the newly built wall platform called the Bott. A century later Stadtsteinmetz Arnold von Gülich rebuilt it in stone, following plans Pasqualini had drawn decades earlier. After changing hands several times, the tower became a meeting place for student fraternities until 1945, then served youth work before becoming the home of the socialist youth organisation Die Falken. Visitors find the cylindrical tower standing free on its mound, ivy now removed to reveal the round-arched windows and the lower arcade. A narrow path leads up the grass bank to the mill’s base, where the old wall fragment leans against the slope. The surrounding street is quiet, lined with modern buildings and one protected institute by Wilhelm Riphahn. From the top of the slope the view stretches across rooftops towards the cathedral spires, linking the medieval past with the living city.
