The watermill is an early industrial cultural relic.
Not much information about its history exists. It is assumed that the mill already existed in companion with a Burghof, which was given to Wilhelm von Nesselrode in 1502 and was destroyed during the war in the 16. Century. In the middle of the 19. century, the mill was bought by the family Reuter from the Earl von Nesselrode. The Reuter family was mentioned as the lessee of the mill in the beginning of the 19. Century. The mill was closed in the 1950s. In 1989 the “Holzlarer Mühlenverein” was founded. The society bought the mill and restored it. Today the mill is one of Bonns monuments and has historic preservation.
