Grundermühle

In the 16th and 17th centuries, the Bergisch manor "Grundt" belonged to the noble von Steinen family, who also owned estates in the Jülich area and others in the "Bergisches Land". The Bergisch manor "Grundt" included the Schümmerischer Hof (the Schümmerich farm lies not far from the road from Unterommer to Reudenbach near Linde in the municipality of Lindlar), Haus Grund itself (Haus Grund lies about 500 m from the Grundermühle on the Kürtener Sülz in the direction of Hommerich in the municipality of Lindlar, now a horse farm) and the Grundermühle, which was built as a grist mill for the noble owners' own use on the Kürtener Sülz. It must have been a small mill operation. The last owner was Clement August Freiherr von Weichs zu Rösberg and his wife Clementina Augusta von Steinen. After her death on October 7, 1769, the estate was divided among her sisters. The youngest sister, Odilia von Steinen, received the "Grundt" manor, which also included the Grunder Mühle mill. In 1774, the house was rebuilt and the mill enlarged. Odilia von Steinen married Baron von Waßenaer and initially made her home at "Grundt" for a short time.

In 1785, the entire estate was sold to Hermann Ossenbach for 16,000 Reichstaler. This included the mill, farm, land, garden, bushes, meadows, hunting and fishing. Hermann Ossenbach kept the mill and the fishery for himself. He sold "Grundt" (now Haus Grund) to Hermann Irlenbusch and the Schümmerischer Hof to Görgen Breidenbach. The "Grundt" manor was thus finally divided into three parts. Hermann Ossenbach enlarged the farm, expanded the mill and built a new barn. When Hermann Ossenbach died in 1859, many heirs laid claim to the estate. As a result, the estate was auctioned off. The co-heirs Wilhelm, Franz, Jakob and Melchior Ossenbach bought the estate at auction and farmed it together.

After disputes, three brothers leave the estate in 1850 and Melchior Ossenbach becomes the sole owner. When he dies childless, his widow sells the estate to Josef Kerb from Kürten on September 1, 1871. He was born on March 31, 1851 in Bergisch-Gladbach and was married to Amalia Hoffstatt from Kaufmannsommer.

The new owner Josef Korb built a new mill pond and thus had enough water power to expand the oil and grinding mill to include a bone mill. He expanded the agricultural business by purchasing some additional land in Selbach. Josef Kerb was elected mayor of Kürten in 1855. He set up his office at the Grundermühle and administered it for around twenty years. As his official duties became more and more extensive, he leased out his property. By 1903, three tenants had taken turns. In that year, he handed over his estate to his son-in-law Wilhelm Bosbach . His only daughter Gertrud Laura, born on June 24, 1860, had married Wilhelm Bosbach in 1884.

When Wilhelm Bosbach took over the estate in 1903, the "Bosbachs" came to live in the mill and on the farm. In addition to the mill and the farm, Wilhelm Bosbach took over an inn and remodeled the property. He built a new weir, a new water wheel, enlarged the bone mill and built new and spacious sheds and stables to replace the old ones. The marriage produced five sons. When Wilhelm Bosbach died on January 25, 1924, his son Klemens (born September 19, 1890) and his wife Anna Bosbach from Offermannsheide took over the estate. Klemens Bosbach junior (born July 4, 1920) took over the estate in 1958 and his son Klaus (born February 3, 1963) in 1985. The property was leased in 1995.

The mill was shut down in 1956 and converted into a restaurant dining room in 1963. The mill wheel was renewed in 1983, but was no longer functional. From 1983 to 2000, it was electrically driven for visitors to the restaurant and the mill wheel terrace. In 1969, the farm was converted from agriculture to fish farming. The fish farm was operated until 2011; the restaurant closed in 2015. The building has been used for residential purposes since 2016. The pond complex is partly rented out and the ponds next to the house are used for recreation by the tenants. Ornamental fish, geese and ducks are now at home here.
