Most of the aristocrats at the court in Bonn had manorial possessions in the surrounding area, including an older or newer castle and more or less extensive grounds. This is where, on their walking tours through the region, tenor Johann van Beethoven, his son Ludwig and violinist Franz Georg Rovantini could be sure of a friendly welcome.

In Flamersheim, they visited the Cologne Electorate's chamberlain, Baron Friedrich Wilhelm von Dalwigk. As Bonn master baker Gottfried Fischer remembers, he was "one of the most handsome cavaliers at the Bonn court". Moreover, he had a daughter who "was equally beautiful" and who, like her father, loved music.

In Oberdrees, they stopped off with a relative of the Fischer baker's family. Presumably, Ludwig van Beethoven still managed to see the Rheinbach town wall, which was only torn down in 1820.

Les nobles de la cour de Bonn often possédaient dans les environs une seigneurie dotée d'un château ou d'une forteresse et de terres plus or moins étendues. During their excursions, the tenor Johann van Beethoven, his son Ludwig and the violinist Franz Georg Rovantini received a warm welcome.

À Flamersheim, they paid a visit to baron Friedrich Wilhelm von Dalwigk, trésorier under the electorate of Cologne. Il était, comme se souvient le boulanger bonnois Gottfried Fischer, " l'un des plus beaux gentilhommes de la cour de Bonn ". His daughter was "just as ravissante" and liked music as much as his father.

In Oberdrees, they stayed with a parent of the Fischer boulanger family. Ludwig van Beethoven had to see the parts of Rheinbach, which had only been demolished in 1820.
