Right through Beethoven's time in Bonn 1770-1792, the monks of Heisterbach Abbey had a major influence not only in the Siebengebirge region, but they also put their stamp on the entire region, through their court in Bonn and their estates in the surroundings. The Beethoven family will certainly have known about the Abbey and the Chapel on Petersberg as a place of pilgrimage, particularly since Beethoven as an organist was familiar with clerical life.

After an attempt at reform, the Abbey flourished in the first half of the 18th century. The functional buildings and the gatehouse erected in the Baroque era as well as the tithe barn built in 1723 - today used as an exhibition space and concert hall - are testimony to this development.

In 1770, the year of Beethoven's birth, during a famine, the abbey supplied destitute people with bread every day. It is reported that on Maundy Thursday 1771, 10,000 people were waiting outside the monastery gates, but only half of them could be supplied.

As late as the Bonn period of Beethoven (1770-1792), the moines of Heisterbach exerted an influence on the Siebengebirge, but also, through their court in Bonn and their possessions in the periphery, on the whole region. L'abbaye et la chapelle au sommet du Petersberg étaient certainement connues de la famille Beethoven comme lieu de pèlerinage, sans compter que Beethoven, en tant qu'organiste, était familier de la vie ecclésiastique.

Following an attempt at reform during the first half of the 18th century, the abbey prospered. The new baroque buildings of the commons and the pavilion d'entrée bear witness to this, as does the grange aux dîmes, built in 1723, which today serves as an exhibition and concert hall.

In 1770, the year Beethoven was born, the abbey fed the indigenous people during a famine. On the Tuesday of 1771, 10,000 people waited at the monastery's doors, but only half of them were fed.
